Rubber gasket for standard locks

I have been looking for these washers for a bit. Finally found the correct washer. Other vendors sell just a plain rubber washer for this application , nothing like this one. It is original equipment quality and fits perfect. Fast shipping too. Thanks a bunch.

So glad I found Ultimate Security Devices website and these are readily available. The lock gaskets on my 9 month-old RV were already failing and water was getting into the hatch doors. Looked like smog-rot as the hatches were made in Los Angeles. Fit perfectly and no more water intrusion.

Perfect replacement for the original seals on the outside cabinet doors. Only other option was to replace the entire lock.
