Coupler Lock Measurements

The Blockhead coupler lock from DeadBolt obstructs access to your trailer coupler to prevent would-be thieves from hitching your trailer to another tow vehicle and driving off with your gear.


Durable Construction

This heavy-duty coupler lock is constructed of extruded, tempered aluminum making it strong and durable. The lock housing features a double nickel chrome finish and the shuttered keyhole protects the lock from the elements.

Works as advertised and will make a good deterent. Combined with the feature of matching keys, the lock allows me to use just one key for all the locks I use. 21123

Very nicely designed, works perfectly with my trailer. 69774


Comments

FYI...In looking at your picture what thieves have been doing in our area is just unbolting the entire coupler and bringing their own. I can see the two bolts in your picture which could be undone in about 1 minute. These need to be secured too.

works great - not sure I really needed it but it is that most effective hitch blocker 548244

by:

Four Stars because nobody has tried to steal it. Yet. However, I'm pleased with the fit on my 1 7/8" trailer tongue. I feel pretty sure a sledge hammer would knock it off, but how many thieves are packin' sledge hammers?! I also put a Masterlock on the trailer latch. At this point, I would recommend both! 510840

still working as designed. Very pleased.

Great lock. simple to use. I had one of other over the top locks for the hitch.. and this is less cumbersome. 150462

by:

The service was excellent. I had purchased other items keyed alike and when they arrived I realized that I had forgotten the blockhead coupler. I called and they were very attentive, providing me with the information I needed to make certain I ended up with the correct coupler, and keyed alike to the items previously purchased. It arrived at the time they mentioned and it works great. 145245


Comments

They are still in use and working great, as though I just purchased them. Additionally, they maintained their appearance and do not look as weathered as they should look.

The Blockhead Coupler Lock is a well-made product that provides a greater sense of security for my Teardrop Trailer. I felt that a padlock was security enough until I purchased this product. I feel more confident about the security of my trailer when I leave it on its own. I like having a secure lock made of tempered aluminum rather than steel. 74191

The function of the product is excellent but the appearance is not. The unit I received must have been returned from someone because it was only taped into the packaging (not sealed) and the front of the unit is chipped up. It's ok. It works and that's all that really counts. 55119

Fits my 1 7/8 coupler on my harbor freight folding trailer. Slightly loose but holds securely enough. Will not be able to pry off. Easy operation and like the dual sided cut key. 46424

The blockhead lock is light weight but heavy duty,the key is cut like an automotive key so you can insert it without having to worry if the teeth are up or down.Great feature when its dark out.The sleek design looks good too.Its giving me great peace of mind knowing it will protect my investment...Also will not rust,awesome unit.. received product quickly, will def use etrailer in the future.... 28191

I especially like this product as you only need the key to unlock it. You don't need the key to lock it on the trailer and that is different than most I look at. Order process was easy and the product arrived very quickly. Very satisfied Larry 22269

by:

This is a compact yet very strong built lock. It is a one piece design so you don't have to worry about loosing or misplacing a part. Easy key access and the dead bolt lock is sealed to protect it from dirt. Highly recommend this product. 19515
