Fits under the seat of most RIGID FRAME wheelchairs. (This does not fit under wheelchairs that fold because the crossbar support is in the way.) Large capacity main compartment holds notebooks, jacket or even a LAPTOP COMPUTER! Main compartment has Velcro-like hook and loop closure; open by pulling forward on the web loop or by slipping a hand under the front flap. (Gussetted opening helps prevent articles from falling out when accessing main compartment.) Front zippered pocket is convenient for wallet and keys. Ring-type zipper pull is particularly helpful for those with limited hand dexterity. Designed to hang under the wheelchair seat using a special attachment system. Four web straps, each having part of a buckle, are attached to the horizontal frame bar of the wheelchair, which in turn slip into the other portion of the buckle on the Under Wheelchair Pack. Remove the Pack by pressing on the center release button of each buckle. Made of durable, weather resistant packcloth.
