Better Bifold Bifold doors can be a nightmare to install — drilling the pins, adjusting the flimsy bottom pivot, and what about the makeshift carpet riser you always have to fabricate out of a scrap of pine? The Johnson 1700 Folding Door Hardware Kit promises to make the bifold installer’s life easier. For one thing, the top track hangs the entire weight of the door on surface-mounted brackets — no more drilling pivots and guides into the door. The rugged track is easy to mount and adjust, and, best of all, the bottom bracket mounts to the doorjamb, not the floor. The 1700 costs $15 to $25 per kit, depending on door size. Contact: L.E.
