I was looking for a prettier bathroom door and this was a great find. It comes with a white knob but I changed it out.

Do you want a hidden room or a safe room? Well, now you don't have to pay custom prices or suffer long delays to do it! Conceal a seldom-used room, create a hidden safe room, or turn a door into a functional storage/display area with an Invisidoor bookcase! Our Invisidoor hidden bookcase door kits come unfinished, assembled, and ready to install with our unique pivot hinge.

Not intuitive to install the first time, but it eventually made sense and the subsequent installs were very easy. Very heavy duty and handles a solid core door with ease. NOTE: The thickness of this hinge WILL leave a gap at the top of your door. If you're using it for a door that will swing in, you can place the top moulding slightly lower, to mask the gap. If yours is a swing-out door, or you otherwise don't want a gap between the top of the door and the bottom edge of the top frame, you'll want to choose a different type of hinge.. Thad. Fairfax, VA.

ADAPTABLE TO ANY SITUATION - The Compack 180 System can be installed without any need for modifications to the walls. No masonry or carpentry work means no added costs with respect to traditional door systems. The reduction in clearance requirements eliminates the problem of interference between doors.

I like that fact that the door can fold flat against the wall and be out of the way. It works perfectly in the space like I envisioned it. The only thing that took a star from my review was that the knobs were not as pictured and the knob screws included were too short to be used. Not a big issue and can be easily fixed by using something else to replace. Just an fyi… a door frame doesn’t come included so I needed to figure something out on my own to install the door. The frame issue was probably just me misunderstanding the description of the included parts and my misconception that it would be included. But all in all, I’ll still recommended this door and I’m happy with it.. Shirley. Alhambra, CA. Sun Mar 29 2026

This cabinet hinge collection is designed for corner cabinet applications, offering two opening-angle options to meet different installation needs: 135° (Non Soft Close) and 165° (Soft Close). -- Both hinges are commonly used in lazy susan cabinets, L-shaped corner cabinets, and corner base cabinets, providing reliable performance and smooth door operation when properly matched to the cabinet configuration. -- The 135° hinge is intended for door-to-door connections, allowing two cabinet doors to fold and open together in corner cabinets. -- The 165° hinge is designed for door-to-cabinet frame (face frame) installation, allowing the inner door to swing open wider for maximum access and improved usability. Please select the correct opening angle based on your cabinet design and door connection method to ensure proper fit and function. Quick Selection Guide ✔ Choose 135° hinge if your cabinet uses two connected doors ✔ Choose 165° hinge if your cabinet requires maximum opening and soft close ❌ Do not use a 135° hinge for door-to-frame installations ❌ Do not use a 165° hinge for door-to-door connections

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. Do not overtighten, turning past 4 hole positions will cause this item to fail.
