The Safety Cover D-Spring is 5 inches long and made of stainless steel. The D-ring end snaps over the anchors, and installation or removal requires a special installation tool (tool sold separately). Price is per spring.
The springs are designed to securely hold your Safety Cover in place throughout the winter. They can be used to replace old springs or for a new installation and are ideal for installations where normal springs will not work. They are ideal for installations with only 2-1/2 to 3 feet of decking around the perimeter of the pool.
