If you use your air mover to float carpet, this kit is a must. When you use the OmniDry Carpet Clamp kit, you can securely clamp the carpet to the snout of the air mover to prevent the carpet from flapping and prevent damage to the carpet. The clamp assembly mounts to two anchors molded into the front of all OmniDry airmovers. The two screws required to mount the clamp are included in the kit. Four rivets are also included to mount the clamp on other models of air movers without the molded in anchors.
