Steel A Clamps like these 4" clamps from Kupo, with black handles and tips, are virtually indispensable on set. Whether it's to keep rolls of seamless from unfurling or for holding bounce cards and reflectors on stands, A clamps are ubiquitous on production sets.
Shown here in a 4" size, this set of four spring-operated clamps are characterized by comfort, strength, and functionality. With features like PVC-coated handles and tips, they protect surfaces from getting scratched, are more comfortable to grab than bare-metal clamps, and provide a convenient and fast mounting solution in all kinds of situations.
