There are two different ways to make a top cap for your V-Interlock Blocks. The first is with a Top Cap Insert. The Top Cap Insert is placed lengthwise into your existing six foot block form. The insert will create a 12” high cap with chamfered edges and is flush with the sides of the blocks underneath it.

The second way is with a separate Top Cap Form. This form creates a top cap that is 26” wide x 6’ long x 6” high with a 12:2 pitch to center peak (8” thick at center) and 1 inch overhang on each side of block. It is poured upside down and flipped over using the trunnions on each end.
