Convert your hinged door into a self-closing door with Prime-Line safety spring door closer. This surface mounted door closer installs in minutes! Use this spring door closer on doors that weigh up to 150 pounds These closers are not handed, so they can be used on both left and right-handed hinged-swinging doors. The door closers feature an adjustable closing force and speed. Constructed of diecast materials with a white painted finish, this safety spring door closer can complement any style door. Each closer is U.L. listed with a 1/2 hour fire rating. These closers operate in a pushing-closed manner, rather than in a pulling-closed method, and they do not have a hold open feature. Distance of travel: The closer arm of this safety spring closer has the ability to swing a full 180 degrees, but once it is mounted in place, the door’s distance of swing will be reduced to the point of where it makes contact with the bullet-shaped housing of the closer. All fasteners and installation instructions are included with this item. For lubrication, avoid using WD-40 which actually breaks down lubricating grease. Instead, apply white lithium grease to internal compressing springs if desired or necessary. Other colors/finishes include: Black, brown, chrome plated and satin chrome plated. For a rust and weather resistant closure, consider model numbers KC50HD (white) and KC57US (brown) which are suitable for outdoor/exterior use, designed for use with lightweight gates and screen doors.

Are you having trouble sliding your screen door open or closed? Have you checked your rollers/roller assemblies? Don’t replace the entire door. For a fraction of the cost of a new door, replace those worn-out rollers. This high-tension steel spring roller assembly fits onto the Columbia Uni-Fit series door. This roller assembly has a 1-inch diameter high-density polyethylene roller mounted in the housing. The flat steel spring end catches onto the inside of the door frame while the flat edges of the two tabs extending out in front of the roller restrict the roller from retracting too far up into the door frame as it rolls. This sliding screen door roller assembly insert has a thinner high-density polyethylene frame than the Prime-Line part B 646. It has an adjustable high-density polyethylene inner housing and high-density polyethylene roller. The assembly inserts into the bottom or top of the sliding screen door using the included screws. The roller adjusts to the correct position needed. This style is found on Columbia sliding screen doors but is also used by a variety of other sliding screen door manufacturers. Please note the dimensions and design when compared with an old roller. Order yours today and have your door slide like new.
