Help CenterParallel clamps are designed to apply a large force to an object while keeping the clamping heads perpendicular to the clamp bar, resulting in precise joints and glue-ups. Pipe clamps work similarly, but due to the nature of a pipe, they can bend when pressure is applied, resulting in bowed boards and generally non-square glue-ups.
Parallel Clamps are designed to address the issues found with other clamps. The clamp bar is designed to resist flexing along the bar's length, ensuring no bowing across the glue-up. The large clamping heads spread the clamping pressure out, minimizing indentations from the clamp faces and providing even pressure. The clamping head on the parallel clamp also ensures that the two clamp faces are parallel and perpendicular to the clamp bar.
So if the primary purpose of the clamp is to be parallel and square, then why are the BORA parallel clamps not square? Our parallel clamps have clamp heads that are angled slightly inward. The design allows the clamp heads to 'set' at 90 degrees once pressure is applied to the clamp. This design stops the clamping heads from flexing outward, keeping the clamp faces parallel throughout the gluing process.
