powerlock toys

If they are both powerlock products, they certainly should

I don't recommend any of the powerlock/vac-u-lock products! They don't have the reputation for great stability and there's not as great of a selection of dongs that will work with the patented systems. An O ring harness will surely do you better!

I do agree with Veteran! Powerlocks are crap!You'd better spend your money on a good O ring harness and you'll have WAY more quality dongs you can use with it.

i don't worry my head bout that. find that strap that will let you produce the power that is needed for the lovely strokes and meaningful thrusts. it worked wonderfully for me and my steele.
