PCSL Plywood Clip — APA-Recommended 1/8" Gap Spacing for Roof Sheathing
The PCSL Plywood Clip is a 20-gauge galvanized steel panel clip designed for quick, easy installation between plywood panels in roof sheathing or panelized construction applications. It provides structural support between panel edges and reduces normal plywood deflection across the span. The clip's embossed dimples function as a built-in spacer, automatically establishing the APA-recommended 1/8" gap between adjacent panels without the need for separate spacers or layout tools.

Unlike loose spacers or field-cut blocks, the PCSL Plywood Clip combines structural edge support and precise gap spacing into a single stamped-steel component, eliminating a separate layout step. The 20-gauge galvanized steel construction provides corrosion resistance appropriate for roof sheathing environments where moisture exposure is a factor.
Key Features & Benefits
Built-In 1/8" Spacer
Embossed dimples on the clip body automatically set the APA-recommended 1/8" gap between plywood panels. This removes the need for separate spacers and ensures consistent panel spacing across the entire roof deck without additional layout time.
Structural Edge Support
The clip provides structural support at unsupported panel edges between framing members. This reduces normal plywood deflection between panels, contributing to a stiffer, more uniform roof deck surface.
Increased Allowable Sheathing Span
With the PCSL clip installed, the allowable sheathing span increases from 28 to 32, allowing contractors to use the same panel thickness across a wider framing layout where code permits.
20-Gauge Galvanized Steel Construction
Fabricated from MAS 20-gauge galvanized steel, the clip resists corrosion in the moisture-prone environment of a roof assembly. The gauge provides the rigidity needed to maintain panel alignment under load.
Fast, Easy Installation
The clip is designed for quick installation between panels during sheathing, requiring no fasteners of its own. This speeds up the sheathing process on large roof decks where hundreds of clips may be required.
Common Applications
Roof Sheathing
Installed between plywood panels at unsupported edges on roof framing to provide edge support, control deflection, and maintain the APA-recommended 1/8" expansion gap across the deck.
Panelized Construction
Used in panelized building systems where plywood panels meet at unsupported edges and require a clip to maintain structural continuity and proper panel spacing.
Compatible Materials
- Plywood sheathing panels (1/2" thickness for this variant)
