Sliding Barn doors are an ideal solution for saving space and creating a unique decorative design theme. Swinging doors can take up more room， and pocket doors can be difficult to install and maintain. Barn doors are simple to install using the mounting hardware included in this kit and the easy-to-follow instructions. Precision ball bearing rollers allow for smooth and quiet operation and are attached to heavy-duty 0.235 in. thick cold rolled steel carrier brackets that mount to the top of the door. Unlike other lower quality kits out there， this system is super strong and will work with nearly any door material (wood， fiberglass， steel， other metal， etc.).Find the BARN DR KIT TOP-MNT S-NK at Ace.
