Ever have a project that requires an 80" long clamp? You don't have to invest all that money on a clamp that you will only use once. If you already own K-body® clamps then this is a must have item for your workshop. The Extender will allow you to take any two K-body® clamps and turn them into one long clamp. Example: two 40" clamps will make one 80"clamp! Durable construction with no loss of strength or clamp parallelism. The Extender does not interfere with the top edge of the bar,allowing your stock to stay nice and flat during glue up. The K-body® Extender is perfect for large, oversized glue ups.
