EASY. SIMPLE. EFFECTIVE.
The granddaddy of all block forms, the V-Interlock block has been used for years in the industry as the go-to block for straight-forward, get-it-done-now applications. These blocks are perfect, and most commonly used for industrial applications such as batch plant fencing and product divider bins.
A raised "male" V notch runs along the top and down one side of the block while an inner "female" V notch runs along the bottom and up the other side. V-Interlock blocks are the only blocks to interlock on all four sides.
