Gee that's sweet dude, most of em I've seen were 6', not 4. Usually they have adjustable stops at the ends, i read the literature on this one and don't see an answer. I would callHydrofarmand simply ask them if it has adjustable stops. Peace
My hydrofarm rail is a 6 footer didnt know they had a 4 footer I knew about the 2 ft and 4 ft extension though. Mine stops the pulley at the end of the rail and then the edge of the reflector goes half way past.Meaning the rail I have is 6 foot and lets say the reflector is 2 feet long 1 foot goes past the rail end so its actually going 8 feet total 1 foot past each end of the rail.
You don't need it for a 4' room. You need to stop it one foot from the wll, so even with stops, which I doubt they would put on a 4' track, your light would only travel 2'. Kinda wasted. VV
hahha yeah it wont fit you would have to probly make it smaller2ft maybe 3ft. i dont know if its possible to mod it unless u can tig weld aluminum. i could.... well any way i have a 4 ft light rail and i was haveing problems with it hit ing the walls and my room is 60 inches wide. so i moved it long ways.now it works fine
