Video Transcript for Master Lock Padlocks - Universal Application Padlock - ML40D Review
Speaker 1: Today we're gonna take a look at the Master Lock stainless steel padlock with the three-eighths inch diameter shielded shackle. Now this shielded padlock will protect your shackle and your gear. It's a hardened steel shackle for extra protection. The lock cylinder uses a four-pin lock cylinder, which is pick resistant. The whole body on this lock is stainless steel, so it does resist corrosion.Now it does include the two keys. And what's a nice feature on this is the keys cannot be removed unless the padlock is locked.
So if we take our key, go ahead and put it in, unlock it, just like that, you can see it unlocks it. Now you can hook it up to what you need to, and the key will not come out when it's unlocked. And then when you go to turn it to lock it, the key'll come right out.Now you can also order multiple locks keyed alike if you need be. We do have that option available on the product page. There's a drop-down menu that you can select the inaudible 00:00:49.A few specs on this.
The overall width of this lock, edge to edge, gonna be right at two and three-quarter inches. Again, the shackle diameter is three-eighths of an inch. The total shackle length is three quarters of an inch. Now the opening right in here with the shackle closed like it is now is three quarters of an inch wide and five eighths of an inch tall.But again, just to show you, you take your key, put it in there, open it up, go ahead and lock it, and take your key right out.But that should do it for the review on the Master Lock stainless steel padlock with the three-eighths inch diameter shield shackle.

I Love the hitch. The lock didnt work with the pin diameter of the B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter Item BWRVK3500, so went a different route.

As per selection offered by etrailer.com of three discus Master padlocks with 3/8" shanks keyed alike, we are very pleased with the quality of the product received, as well as the fact that no hardware stores in the Reno/Sparks NV area carried a three pack of these types of locks keyed alike. This makes for very simple ease of use in our situation as well as having the security of discus locks in our application. Also, no hassles or issues in ordering these locks on line. Delivery info on web site was straight forward, accurate and timely. Will considering using etrailer.com again in the future. 477363

Clumsy and sticky to lock and unlock. I ended up putting a dry lubricant in the lock to get it to function smoothly. I am conerned that under adverse weather conditions the lock may not work smoothly. etrailer was terrific, arrived quickly, no issues, all locks properly keyed. I still use etrailer and it has been an excellent resource for trailer issues. 404894

Ask the Experts about this Master Lock Padlocks
- Recommended Trailer Coupler Lock for a 2-5/16I want to start off by saying that any trailer lock that you purchase will never be able to fully secure your trailer from a thief. If they are determined enough to bring equipment with them to remove a lock then given enough time they will be able to remove a lock. This will be the case no matter what you what you are looking to put a lock on. With that being said, the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 that you referenced is a great lock that has received many great reviews...
view full answer... - Master Lock Padlock to Work With Blaylock EZ Lock Trailer CouplerThe Master Lock 970DPF will not work with the Blaylock EZ Lock Trailer Coupler # BLTL-33; instead you would want to use the Master Lock Padlock # ML40D.

- Can Multiple Master Lock Hidden Padlocks Be Ordered With the Same KeysThe Master Lock Hidden Padlock part # ML6271 does not come keyed alike if multiple locks are ordered. We do have pad locks with a 3/8" shackle that can be keyed alike, the Master Lock Stainless Steel Padlock part # ML40D but none of them have the same hidden design as the above.
view full answer... - Can Blaylock EZ Lock Trailer Coupler Lock Fit Demco Channel Style Coupler # DM13203-95Yes, the Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 that you referenced does fit the Demco Channel Tongue Trailer Coupler # DM13203-95 that you referenced. The max diameter shackle you could fit through the hole on the 3/4 inch long pin is 3/8 of an inch like what the Master Lock Stainless Steel Padlock # ML40D has.
view full answer... - Will the Replacement Handle Latch for Cam-Door Lock Part 158-102 Work With a Puck Style PadlockYes, the Replacement Handle Latch for Cam-Door Lock part # 158-102 will work with a puck style lock like the Master Lock Stainless Steel Padlock part # ML40D so long as the shackle does not exceed 1/2" diameter. I have attached a photo of this for you.

- Inner Dimensions of the Blaylock EZ Lock Coupler Lock # BLTL-33I pulled the Blaylock EZ Lock Coupler Lock, # BLTL-33, from our warehouse and took some measurements for you. The inside width of this coupler lock is 4-3/4 inches. From the base to the bottom of the pin, it measures 3-1/8 inches (see photo). If you do not have a padlock yet, I recommend looking at the Blaylock EZ Lock Coupler Lock with Padlock, # BLTL-33-40D. This is the same coupler lock, but it includes a stainless steel padlock. You could also just purchase the lock separately as...

- Can Lippert # LC236558 Underchassis Double Bin Storage Unit Be LockedThe bins don't include locks, so you would need to devise some way of locking them. A locking hasp like part # 720DPF with a padlock like # ML40D would be a good solution.

Just select the keyed alike option from the drop down menu near the add to cart button. Select the amount you want in the quantity box and all of the locks will be keyed the same.

Since you mention you do not have the hook type lock like # SR03807 then this is likely to be the part you need. According to my contact at Thule, who made the SV cargo boxes for Sears, the complete replacement lock assembly like yours is not available as a replacement part. You may be best served by installing an exterior lock...

- Recommended Trailer Coupler and Padlocks Keyed AlikeFor your coupler locks to enable you to get all your locks keyed alike, I recommend the Blaylock EZ Lock Trailer Coupler Lock for 1-7/8", 2", and 2-5/16" Couplers - Aluminum # BLTL-33-40D. This will use the 40D Master Lock Padlock and they can be keyed alike to each other by selecting that from the dropdown on the product page and adding the quantity desired. To get the locks all keyed alike you will do the same thing with # ML40D. The easiest option is to order the total number of...
view full answer... - Lock for the TEM AutoLock # SM2516NP Gooseneck CouplerThe TEM AutoLock # SM2516NP coupler is 5 inches across, and the hole for a lock to pass through is 1/2 of an inch in diameter. I have checked the pass through locks that we have, and there are not any that are long enough, or the correct diameter, to work for this coupler. However, we do have several padlocks that could be used on this coupler in place of the pass through pin. These padlocks could be used while the trailer is connected and being towed, or not connected. For this application,...

This can be used with the same locks as the Blaylock EZ lock # BLTL-20 that has a width of 3-3/16 inches on the inside. You can use the Master Lock Stainless Steel Padlock with Shielded Shackle - 3/8" Diameter Shackle # ML40D which can be keyed alike to get the desired number of locks.

- Padlock Size and Recommendation for Use with EZ Lock Trailer Coupler Lock # BLTL-20For a lock for the EZ Lock Trailer Coupler Lock # BLTL-20 we actually recommend disc-style padlock # ML40D both of which have a 3/8 inch diameter shackle. I have linked a video review of the EZ Lock coupler lock and in it our video team shows this style lock being used.
view full answer... - Can Puck Lock Be Used with Blaylock EZ Lock Trailer Coupler Lock # BLTL-33The Blaylock EZ Lock Trailer Coupler Lock # BLTL-33 is designed to work perfectly with a standard padlock, but I think the typical opening size on the back of a puck lock will be a bit too small to fit over the end of its pin/shank. The pin/shank on this lock has a 3/4" diameter, while for example the opening on the Master Lock Puck Lock # ML6271 we have available has a height of just 19/32", which wouldn't allow it to mount over the pin. Your best option is going to be with something...

view full answer... - How To Determine Fit of the Lippert Underchassis Double Bin Storage UnitIn order to determine fit of the Lippert Underchassis Double Bin Storage Unit you need to measure the distance between the two spring seats on the axle. If this distance is 68-1/2" wide then you can use part # LC175180 or if this distance is around 72" wide then you can use part # LC236558. If you have a different distance then modifications would need to be made in order to fit. The Lippert Underchassis Double Bin Storage Unit does not have locks but since the bins install under the...

The latter doesn't have any restrictions of the width of the coupler.

- Recommended Hitch and Trailer Couple Locks that Can be Keyed AlikeWe can get some of it keyed alike but not every piece. I recommend using our etrailer.com locking hitch pin, part # e98881, and coupler lock, part # e98888. These can both be ordered keyed alike to one another. We don't offer any padlocks. Instead I would get two Masterlocks using part # ML40D. They can be keyed alike to each other but not the same as the etrailer.com locks.
view full answer... - Available Types of Trailer Coupler LocksWe do offer coupler locks that allow you to secure an unhitched trailer. These can be seen on the linked page. These locks include types like the EZ Lock Trailer Coupler Lock # BLTL-20 which works along with a pad lock that you supply, such as # ML40D. We do not offer any lock products intended to secure a hitch ball to a ball mount. Usually hitch balls will be torqued (according to the manufacturer's instructions) to a degree that would make it hard to unscrew the nut that holds the...

It cannot be ordered with different locks pre-installed but you absolutely can add supplementary hasps and padlocks to maintain security for the water-quality equipment you need to house within it. We do offer many such lock and hasp parts but the ones I suggest are the Master Lock Contractor Grade Double-Hinged Hasp # 722DPF because it will allow installation with...

You may also be interested in the Blaylock EZ Lock Set Screw Lock on Gooseneck Coupler # BLTL-51 to further secure your gooseneck coupler.
