This is a pack of TWO drilling jigs, with free US shipping. You use this jig to drill through the j-channel, in order to keep consistent spacing for your LED lights. The spacing is approximately 2.5 inches between lights. The jig works with 12 mm LED lights, using a 1/2″ drill bit.
Please note: You should only need one jig, but we have included a second jig, in case you run into problems with the first one, or if you have a second person helping drill.
