Bridge Clamps

Bridge Clamps

It can be difficult to achieve an effective seal when using standard worm drive clips with flexible ducting due to the spiral helix. Our bridge clamps are manufactured from 304 Stainless Steel and ‘bridge’ the spiral helix to provide an effective clamp and seal. They are easy to use particularly on big diameters and have rounded edges to prevent damage to the ducting. A range of our bridge clamps are available to buy online at PAR Direct by clicking the link above.


Clamping of flexible ducting with a spiral helix. Bridge clamps are suitable for light, medium, heavy and very heavy duty ductings.


To be able to determine the correct bridge clamp for your application, please use the information and diagrams below.

Right Hand Bridge Clamps: When looking at your ducting from the end on, the helix will be spiralling in an anti-clockwise direction towards you. This indicates that you require right hand bridge clamps.

Left Hand Bridge Clamps: When looking at your ducting from the end on, the helix will be spiralling in a clockwise direction towards you. This shows that you require left hand bridge clamps.
