Ashley (Remap Essex North)would like to know if anyone knows where: I can obtain child proof buckles for 40mm webbing. Or has anybody modified a buckle to be childproof. I have a client who can easily undo her side release buckle. Lockable ones are available in 100s at considerable cost but they need a key not sure that is a good idea. It is for a shower chair I have a solution but replacing the two buckles with something childproof would be much easier.
