What are the Dimensions of the Trimax Puck Lock for Trailer Door Hasps?

Updated 09/30/2025 | Published 09/13/2025

Question:

I am trying to find out the slot dimensions on the back of the Trimax puck lock TMX96RR. You have one video saying it will fit a 2 7/8 wide hasp and another video saying the lock is 2 7/8 diameter. I would just like to know the actual width and height of the slot so I can determine if these will work for my application.

Hey Tim, thanks for reaching out!

The Trimax Puck Lock for Trailer Door Hasps # TMX96RR has an overall diameter of 2-7/8", and the opening is 1-3/4" wide x 3/4" tall. It's also 3/4" deep.

I've attached some photos for you to check out.

Does this look like it will work for you?

@JonG The locks did work. It was faster to get one delivered and try it. Etrailer took 10 days to get a question answered.

@TimP Glad to hear it worked out! Sorry for the delayed answer to your question. I had reached out to Trimax directly and they were less than helpful, so I ended up having to go a different route to find that information.
