The kader groove clamps are designed for use in clear span marquees with kader grooves. We stock 3 sizes of kader groove clamps, these are…

• 70mm
• 90mm
• 120mm

​The above sizes are the MINIMUM size when the clamp is tightened. (I.e. if the clearspan marquee has beams that are 100mm wide you will need a 90mm kader groove clamp).
