Spring clamps are a great multi-purpose tool. These clamps are known for their strength and are made heavy duty from high quality steel with rubber tips and handles that can be positioned easily with one hand. 

Plastic tarp clamps are perfect for attaching your tarp to your 1 3/8" canopy poles. These are a great for hanging a tarp without using the tarp's grommets.

Swivel clips are a good alternative to adding grommets or replacing a torn-out grommet on the tarp. This item has an excellent clamping power and can be used for different types of tarps.
