Looking for Replacement Slam Latch for 3-1/2 inch Square Cut Out  

Published 04/08/2026

Question:

Hi, I have a 2017 Sonic Lite 167 travel trailer by Venture. I need to replace the slam door latch for the storage access. The cutout size is 3.5” x 3.5”. Do you have this latch or a compatible option available? Thanks, Scott.

Hey Scott, the best option we have for a slam latch to fit a 3-1/2 inch square hole would be the Bauer part # BA35HR which is for a 3-7/8 Inch W x 4-1/8 Inch T cutout so you would need to enlarge you hole a little bit.

Thanks! Is there an option that is less expensive? I don’t need a keyless latch, just a latch with a manual key. Please let me know if I have another choice. Scott.

@Scott in that size that's only option. Is there some wiggle room on the cutout size? Could that be enlarged?

@JamesonC Yes, enlarging the hole is not a problem. Scott.

@Scott Should be able to get the part # BA57FR to work then.
