1. Do you have a machine that I can buy so that I can punch my own stainless steel markers??
No we don't have any machines that you can buy and punch your own stainless steel markers. Our markers are made in 316 steel and you need to punch that with a force of several kilos.
2. Can I use ordinary cable ties with PKS markers??
No you can't use ordinary cable ties to mount PKS onto a cable because the cable tie is to thick.
