Thanks. I will try this
You will need 8 clamps per EB. If you want an easier way to make your own, you can buy 4" clamps and cut them down to 1" or get a 48" piece to give you lots more clamps.
The only thing you need to do besides cut them to length is to grip with visegrip pliers and hold in boiling water for a couple of seconds & squeeze slightly to narrow the slot. Plunge into cold water for a few seconds, then release. You'll get the feel of it after doing a couple and testing on a box. I find this a lot easier than trying to cut a slot the right size in pvc pipe.
