Why even bother with tape?!!! This is the best thing for a line ever. Bought a GLD backboard, and drilled this beauty on the bottom of the wood frame of it. Looks fantastic and the wife will never complain about her precious floor being ruined with ugly throw lines! Worth every penny. Just remember to spend about a good 10 minutes with patience. Because you have to screw the two side screws on each end of the laser to tighten it down and prevent it from moving which can be a bit of a pain as the line moves slightly! Other than that, 5 stars all the way
