Silver 20 Inch Galvanized Rust Proof Stainless Steel Round Rolling Shutters Spring

Choose our grey stainless steel galvanized rolling shutter spring for the highest quality and precision. For added security and waterproof protection, this rolling shutter offers an ideal solution. This is the perfect solution for anyone looking for a soundproofing solution or wanting to prevent dust and other airborne particles from entering the home. It consists of a two-part unit. Each half has two springs and is connected by a flexible joint. When the shutter is closed, it is held in place by one spring; when the chain rope is pulled down, the second spring moves slightly and pulls the chain rope down, causing the opposite side to open.
