When We did our door, I drove the rig to the glass shop, so they could cut the upper curve to fit the door. Was just going to get the pieces and put them on ourselves. The shop tech remeasured everything himself, then asked how I planned to mount then and did I have the pieces. He came back out with the fitted pieces, and before I could say anything, had everything mounted and finished. Charged me for the lexan and cutting it. Said he just wanted to make sure I didn't damage the Lexan while I installed it. Said I didn't have any business up on a ladder.
