Q-Snap Frames

Q-Snap frames are made from PVC tubing making them lighter and more
durable than other materials. The clamp design for holding the fabric
is gentle and simple to use. Just lay the fabric over the frame then
gently push the clamps down stretching the material around the outside
of the frame. The ribbed inner surface of the Q-Snap clamps hold the
tension for your preferred adjustment. Simply turn the clamp outward to
tighten or inward to loosen.
