Pro Tip; Install a Sliding Screen Door “LIKE A BOSS”!;  

Not sure what you mean by gear selection

Yeah sure - talking tooling required, roller selection, latch etc. what’s best from your experience and why you chose it.

@s4144095 got it. It is called a KD (knock down) door as it is shipped in a kit if you order online from Amazon or another company. You will need to get your width and height correct. It comes basic with nylon rollers and a plastic handle with latch kit. For install, we loosen the wheels, insert into the track making sure wheels are on the bottom rail, then tighten bottom wheels until about an 1/8” off rail. Tighten top wheels till you like the way it slides. All 4 wheels are adjustable so you may get it as straight as possible. Pretty simple.

@s4144095 and if you are going to buy and cut it to fit you’ll need a miter saw (fine tooth metal blade), we use a chop saw that miters. Once cut, you’ll need the corner hardware with wheels (typically sold separately). Once assembled, you’ll need screen of choice, spline of .150, screen roller and a plastic patio door handle. I hope this helps

@@SkinnersScreens1972 thanks - sounds stupid but the only other thing I would add if you do another one is roller size 1 width/diameter etc. I’ve messed this up a dozen times and would love to see some guided expertise on selection.

It’s a standard sliding patio door. Fits most applications. Pretty standard.

@@SkinnersScreens1972I went to Home Depot and got a replacement one. The only height available was 77’ 7/8” I couldn’t even get it in. The wheels weren’t in the way. It was the actual door. The adjustable ones were also slightly too big for retrofitting.

Big box doesn’t custom size them. You can disassemble one end and cut it down a bit. Just have to be careful
