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. Note that it retains the end interlocks. 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. Loosen the quickbolts on each corner and release the V-notch pan and your block will slide right out. Used with a 45º Top Cap Blockout you can neatly turn a 90º corner.

The T-block is used for creating “T”junctions for partition walls. The block can be used as both a corner block and a T-block. This block has one two-foot section of top V-groove turned 90º and one two-foot section of bottom V-groove turned 90º allowing it to interlock with blocks running above and below it. Because the T-block overlaps the block below it by 2 feet, the 5 foot length will allow you to maintain your running bond after turning the corner.
