Tired of trying to evenly space drawer guides and keep them parallel when mounting them? The Miller FastBlock replaces the commonly used "block of wood" with an adjustable drawer guide mounting system. Simply hold the Miller Fast Block on the back side of the face frame, adjust the block flush with the edge of the face frame, and mount the block to the back of the drawer guide. You can also use 2 Fast Blocks per side to adjust drawer guides for pull outs. Great for face frame cabinets, European cabinets, and pull-outs.

Fully adjustable spacer blocks (up/ down and in/out adjustability)
Durable and permanent
Includes: 2 Blocks
