Anyone have a link for where one can buy Belisle-type safeties for 155 size body-grips?

You can make self supporting safety latches by just using Trapper’s wire. About 3-4 wraps around the spring leading up to the latch, go around the latch a couple times, then 3-4 wraps tight around the spring working away from the latch.

This winter I bought some 330`s and 440`s RBG and I tried this method of wrapping the 14 ga. wire around the spring arm. When I was done for the season, I wasted more time taking the wire off of those springs. There were a few that worked great, but most just sucked. Like they would lock going one way on the spring but spin going the other way, problem was the way I needed to go to get that clip off the other spring arm was the way it would lock in place. I wound up bending up some of those RK safeties, had to straighten those back out. I tried the vinyl tubing method inside the RK safeties and well it was just..........Whatever. It was better better than stock , but not by much. The Belisle safeties are the standard of the industry in my opinion. I have bought Belisle`s at times simply because of the safeties. In the middle of winter, far from help and those traps covered with ice, any brand, cheap safeties just aren`t worth it. Unfortunately Belisle`s are just about priced right out of the market. A bunch of years ago, I started making some of my own Belisle`s style safeties with 11 ga. wire, bending them all by hand and a pliars to replace some of the regular safeties that were getting trashed. They actually worked really well, just a hassle to make and then I sold all my non Belisle traps. I think these RBG` deserve some more testing and have seriously considered getting out the wire and the pliars again. It`s actually kind of incredible in this day and age that there aren`t better safeties out there.

Not all trappers like the belisle safetys.
I like them ok on beaver traps but any box with narrow slots like marten boxes they are no good.
Always having to monkey with them to get them to slide out of the way of the slots after setting. and before installing the trap back on the box
The safetys that swing free are much better on a marten trap like the LDL.

I'm with Boco on this one. I love Belisle body grips but in boxes you have to work the clip out towards the coil end of the spring. In runs, dam crossings, etc. there super.

Yup, I screwed around wasting my time with trying to wrap wire but figured out a far better way and simpler method IMHO to make safeties stay where you put them!

All good points. And yes, I have tried the wire "stop-wrap" and am not a fan. And Boco, I know that the Belisle safeties can interfere with marten box slots, unless you make your boxes a tad wider to accommodate the safeties.
Seldom, that is a fine idea, and I would get busy on doing that to those Bridgers, IF the safeties were even CLOSE to the right length.
