The Simpson PSCA 15/32-in. Panel Sheathing Clip is engineered by Simpson to brace unsupported sheathing edges where plywood panels meet edge to edge without a rafter for support. Inserted over the edges of adjacent panels, this light roof sheathing clip reduces deflection and keeps panels even to maintain a level plane on the structure, while maintaining the 1/8-in. gap recommended by the American Plywood Association to accommodate the natural shrinkage and expansion of roof sheathing over time.

Key Features

• Designed for 15/32-in. panel thickness - ensures a proper, snug fit between adjacent plywood panels with no guesswork, since the clip size matches the panel thickness exactly.
• Quick installation with no nails required - simply slip the clip over the panel edges to save time on the roof and reduce the number of fasteners needed during sheathing installation.
• Provides the APA-recommended 1/8-in. gap between panels - allows plywood sheathing to shrink and expand naturally without buckling, protecting the integrity of the roof deck over the life of the structure.
• Reduces deflection and maintains a level panel plane - keeps unsupported sheathing edges aligned so the finished roof surface stays flat and even, which is critical for proper underlayment and shingle performance.
• Made from 20-gauge steel - delivers reliable structural stiffness to brace panel edges even in demanding roofing conditions.
• Zinc Galvanized (G90) coating - provides corrosion resistance to help the clips hold up against moisture exposure typical in roofing environments.
• 250 clips per package - a bulk quantity that keeps roofing crews supplied across large sheathing projects without repeated restocking.

Why This Product

• Built-in panel spacing you can count on - the PSCA automatically creates the 1/8-in. gap between plywood panels that the American Plywood Association recommends, eliminating the need to measure or estimate spacing by hand on every joint.
• Faster installs with no fasteners required - because the clip slides directly onto panel edges without nails or screws, sheathing crews can move across the roof deck quickly and maintain a consistent workflow.
• Long-term protection for the roof deck - the G90 galvanized steel construction resists corrosion while the clip's design accommodates ongoing wood movement, helping the roof sheathing perform reliably through seasonal changes.
• Trusted Simpson engineering for a critical connection point - unsupported sheathing edges are a common weak point in roof assemblies, and the PSCA is purpose-built to brace those edges, reduce deflection, and keep the panel plane level from installation through the life of the roof.

Frequently Asked Questions

What panel thickness is the PSCA 15/32 designed for?

The PSCA 15/32 is specifically designed for use with 15/32-in. thick plywood sheathing panels. It is important to use the same size sheathing clip as the panel thickness for proper fit and performance.

Do I need nails or additional fasteners to install the PSCA sheathing clip?

No. The PSCA clip features quick installation with no nails required. The clip is simply inserted over the edges of adjacent plywood panels to hold them in alignment.

Why does the PSCA clip provide a 1/8-in. gap between panels?

The 1/8-in. gap is provided to address natural shrinkage and expansion of roof sheathing over time. This spacing is in accordance with the recommendation of the American Plywood Association and helps prevent buckling or damage caused by panel movement.

What type of corrosion protection does the PSCA 15/32 have?

The PSCA 15/32 is made from 20-gauge steel with a Zinc Galvanized (G90) coating, providing reliable corrosion resistance suitable for roofing applications.
