Most of our products are built to work in conjunction with LockGuard complatible cuffs and collars. While such cuffs and collars aren't a requirement for getting the best out of our products, they will enhance the look by rezzing chains between the victim and the device, making the restraint look a lot more convincing.
At the very least most (but not all) of our products will look best with wrist cuffs, ankle cuffs and a collar with at least a front loop (although a back loop is nice to have too). A small number of our products will also make use of upper-arm and upper-leg cuffs.
Chances are you (or your victim) already have the right sort of cuffs. These days most cuffs seem to support LockGuard. For testing purposes, or even for longer-term use if you wish, Z&A have made a set of very simple LockGuard cuffs. You'll find them around our main store. Just keep an eye out for a board or box with this on it:
Antony generally makes use of the Marine Kelley Elegance Cuffs.
