Springlock Base, 12'

120' per order (10 lengths of 12') Springlock is used to attach poly to greenhouse frames. The steel channel is double coated for excellent durability. Unlike aluminum, the base bends easily over end arches, and the rounded bottom fits well with round structural members. The channel accepts 3 springs - very useful for attaching end wall poly or shade cloth. The channel holds up to 4 layers of 6 mil poly.
