Unilock U-Cara Wall Sure Track Corner Insert 2 in. (40 pc./bag)

The U-Cara Backer is a structural building block that is part of the U-Cara Multi-Face Wall System. This revolutionary system makes it possible to design walls, pillars, planters, fire features, grill islands and more, using a wide array of different U-Cara fascia panels to create color, pattern and texture combinations like never before. The patented U-Cara Sure Track Backer blocks feature molded horizontal rails, allowing you to mount U-Cara fascia panels securely on the block. Build single or double-sided vertical elements using the Standard Sure Track Backer block. If your client wants a large retaining wall, planter or pillars, use the Large Backer Block in the setback position to construct walls up to 3 ft (0.9m) high, without the need for geogrid.
