Video Transcript for Master Lock Locks 970DPF Review

Today we're taking a look at the Master Lock hidden shackle padlock, number 970DPF. This lock features a hardened steel solid body. It's very strong, durable and resists corrosion. It has a protected shackle design which you can see right here in the back. It prevents prying, cutting, and sawing. It has a six pin cylinder for maximum pick resistance.

The way this works, pop the key in here, a quarter turn, you pull that out the entire cylinder comes out of the body here. Pop that back in, quarter turn, the key comes out and you're locked right back up. Taking a look at the specs for this item, it is two and seven-eighths inches in diameter. It is an inch and a half thick. On the back, the hidden shackle opening is one and eleven-sixteenth wide from this side over here to this side here, nine-sixteenth inch tall from the top to the bottom here, and it is one inch deep.

The shackle is seven-sixteenth in diameter. If you're wondering what we would use this on, wonder no more. It is the Master Lock hidden shackle padlock hasp, number ML-770. This is perfect for enclosed trailers, vans, trucks, gates, vending machines, that sort of thing. You bolt that onto your gate, your door opens like that to lock that up.

If you notice right here, this large opening here is where your lock is going to go. It's going to go on that side. Once again, pop that open, quarter turn, cylinder comes out shut that in, quarter turn and you're locked. That is not going to open. You want to open that back up, a quarter turn, cylinder comes out, your door/gate is open.

That's all we've got for our Master Lock hidden shackle padlock, number970DPF.

The product was exactly what I needed to protect the trailer / hauler I transport my 2011 Roush Stage 2 convertiable in. Revcently, in the storage facility I keep the hauler, someone damaged the door hasp in attempts to enter it. No entry was gained but now, no attempt will be made, simply because one can not get to the locking hasp . Thanks for the fat shippinf and reasonable pricing !! 25428

It is a similar lock that I have from etrailer.com. Only reason did not give 5 stars is the keys are hitching a bit. Hopefully some dry lube will solve the matter. This annoyance is more a quality control issue from Masters than anything else. Glad the package was opened to make sure the keys worked in the lock. Thank you George for your due diligence. 319912

Lock appears to be great quality. Very heavily constructed. Also, item was shipped the same day, and received a couple of days later. I believe the lock will do the job of securing the door on my cargo trailer. Thanks for excellent product and service. 257192

Excellent product. I purchased it to work with matching hasp. It worked great, I wish this particular lock had a wide enough opening to work on the factory rear latches on my trailer as well. 123335

Ask the Experts about this Master Lock Padlocks
Do you have a question about this Padlock?

  • Replacement Door Lock Latches and Cam Door Locks Recommendation
  • The old Bargman L400 series locks you have on the trailer currently haven't been made for a very long time and apparently due to their rarity and how desirable they are people sell them for quite a bit of money when they can find them. I can't help you find those. For a similar handle lock you could use the Full Size Locking Steel Flush Door Latch # L3980. Cam door latches like part # 383200 usually just lock with a padlock or something like # 970DPF and there really isn't a way to...

  • Availability of Hidden Hasp Locks for Universal Cam-Door Lock # 383200
  • The Master Lock Hidden Shackle Padlock, part # 970DPF will work with the Universal Cam-Door Lock, part # 383200. These locks can be purchased keyed alike. When ordering, simply select the keyed alike option in the drop down menu. Unfortunately, we cannot get this particular lock keyed alike to a different padlock or tongue lock. In the future, if you decide you would need additional locks with the same key number as those you had ordered before, we could special-order them from Master...

  • Availability of Disc-Style Padlocks that Can be Keyed Alike
  • I recommend Master Lock padlock # ML40D. You can get as many of these keyed the same as you want. 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.

  • Dimensions of Master Lock Hidden Shackle Lock # 970DPF
  • I have taken a complete set of measurements on the Master Lock # 970DPF, see the photo I produced for you. Years ago, I worked for a vending company, and we used some of these locks on our machines. I can say from experience that these hidden shackle-type locks are VERY difficult to defeat. The master puck locks are not available keyed alike, but you might be able to have a locksmith re-key them for you, if you are wanting multiple puck locks. Because all the Master Lock coupler locks...

  • Would the Master Lock Hidden Shackle Padlock fit on a Trailer Door Latch
  • Most likely yes, but to be certain I attached a picture that has dimensions for the Master Lock part # 970DPF for you to compare to the latch on your enclosed trailer to see if it would be compatible. If that doesn't fit your latch I would go with the Master Lock Stainless Steel Padlock with Shielded Shackle # ML40D. This would be pretty hard to get a bolt cutter on.

  • Availability of 4 Puck Style Padlocks than Can be Keyed Alike
  • I recommend Master Lock padlock # ML40D. You can get as many of these keyed the same as you want. 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.

  • Comparison of the Diversi-Tech Puck-Style Guard Lock and the Master Lock Hidden Shackle Padlock
  • The differences between the Diversi-Tech Hasp and Hatch Puck-Style Guard Lock, item # DT39002, and the Master Lock Hidden Shackle Padlock, item # 970DPF, are small. Both are quality products. The biggest difference, security wise, is that the Diversi-Tech lock has a hasp that is 3/16 inch larger in diameter than the Master Lock padlock, and the Diversi-Tech lock has a slightly larger opening for a hasp to fit into. I have a set of Diversi-Tech padlocks and they are very well constructed,...

  • How to Replace Lock Core of Masterlock Shackle Padlock
  • To install the replacement lock core set # 297W7000 on a # 970DPF will require you to loosen the set screw of the lock and then disassemble the lock. I attached a picture that details the entire process.

  • Availability of King Pin Locks and Pad Locks that are Keyed Alike
  • The only Fifth Wheel pin locks that we have that can be ordered keyed alike are the CT Johnson DeadBolt 5th Wheel Trailer King Pin Lock, item # KPL. Current pricing is available using the link provided below. I like the DeadBolt brand locks because the service provided by the manufacturer is second to none and rarely, when there is a problem they always do their best to accommodate me and the customer. A Trailer Hitch Receiver Lock, item # 7683, or a Trailer Coupler Lock, item # 7691, can...

  • Does the Master Lock Hidden Shackle Padlock Include a Hasp
  • No, this Master Lock Hidden Shackle Padlock, part # 970DPF does not have a hasp included with it. The hasp is sold separately as part # ML-770.
    view full answer...

  • Can Master Lock part # 970DPF Have Multiple Locks With the Same Keys
  • Each of Master Lock part # 970DPF are keyed individually and do not have the option for like keying. We do have Master Lock part # ML40D that can be keyed alike. I have attached a short video describing the lock and its attributes.

  • Hasp Lock Recommendation that Fits over Handle that is 1-1/4 inch Tall and 1/2 inch Thick
  • I believe we have a solution for you based on the dimensions you listed. The Master Lock Shack Hasp lock part # 970DPF has an opening that measures 9/16 inches tall and 1-11/16 inches wide. Check out the picture I attached to see the full dimensions.

  • Can Different Styles Of Trailer Locks Be Keyed Alike?
  • The Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set - 1-1/4" and 2" Hitches, # 3794DAT is the closest we come to a keyed alike option for all your trailer locks. We don't have the option of the keyed alike shackle padlock. The Master Lock Hidden Shackle Padlock # 970DPF is the only hidden shackle option we currently have. The wheel locks can be keyed like each other, but not like the other locks so you can have multiples of the same part but you can't key the other parts...

  • Will Master Lock Hidden Shackle Padlock Fit Replacement Hasp PLR158-102-A
  • It would be a tight fit but you could use lock # 970DPF with hasp # PLR158-102-A. Worse case scenario is that the swivel part of the hasp would have to be filed down a little and/or flattened a little for the best fit (since there can be slight variations from one hasp to the next).
