These staplers are specially modified for zero impact fastening of our ThermaWire CFH-T heating cables to wood strapping. They feature an un-precedented opening for the wire to fit through and make it virtually impossible to pierce or damage the heating cable. Using any other stapler will void the warranty in the event of a cable fault.

My company has installed many brands of heating cables before we switched to Thermawire. In the past we had to use tedious clips or risk damaging cables with T25 staplers. With Thermawire's modified T37A stapler cable installation is a breeze with no chance of damage from misalignment or impact - you should see the size of the groove where the cable lies! I've used the one I ordered last summer in over a dozen jobs and it still works like new and hasn't hit a cable yet!
