This awning clamp almost completely eradicates that annoying "flapping" noise of the awning fabric caused by the wind. Simply slide the clamping device onto the side of the fabric, attach to the existing rafters or rods on both sides of the awning, turn the handle and fold down to close. The clamp covers keep the fabric taut without damaging it. Finally, silicone tape is stretched around the pole and, depending on the size of the pole, a corresponding raster hole is drilled in. Compatible with the tie strap for added stability using the existing Keder rail. Can be attached to almost all awning systems, regardless of whether round, oval or square rafter poles.
