€¢ Provides a secure environment for sheathing €¢ Support for shrinkage and expansion over time €¢ Galvanized for corrosion resistance The PSCL is designed to brace unsupported sheathing edges when sheathing meets edge to edge without a rafter for support. This light sheathing clip provides a 1/8" gap to address shrinkage and expansion of roof sheathing. Inserted over the edges of adjacent plywood panels, the PSCL reduces deflection and keeps panels even to maintain a level plane on the structure.
