Product Description
Simpson Plywood Sheathing Clips (3/8 inch) by Simpson are precision-formed roof sheathing clips engineered to brace unsupported panel edges where plywood sheathing meets edge to edge without a rafter for support. Fabricated from 20-gauge steel with a zinc galvanized G90 finish for lasting corrosion resistance, these clips are a reliable solution for maintaining a level, stable roof deck surface. By inserting the clip over the edges of adjacent plywood panels, installers can reduce deflection, keep panels aligned in a single plane, and provide the 1/8-inch gap necessary to accommodate natural shrinkage and expansion of roof sheathing over time.
Key Features
- Designed for 3/8-inch panel thickness - fits precisely over the edges of 3/8-inch plywood sheathing panels, ensuring a secure and snug connection without additional fasteners
- Built-in 1/8-inch expansion gap - accommodates the natural shrinkage and expansion of roof sheathing, reducing the risk of panel buckling or warping over time
- Braces unsupported sheathing edges - keeps edge-to-edge panels aligned in a level plane even where no rafter is present beneath the joint, improving overall roof deck performance
- Reduces panel deflection - minimizes movement at panel edges under load, contributing to a stronger, more rigid roof surface
- 20-gauge steel construction - provides a lightweight yet durable clip that is easy to install quickly across large roof sheathing areas
- Zinc galvanized G90 coating - delivers corrosion resistance suited for outdoor roofing applications and exposure to moisture, extending service life
- Made in the United States - manufactured to consistent quality standards
Why This Product
- Solves the unsupported edge problem - when roof sheathing panels meet edge to edge without a rafter beneath the joint, these clips provide the structural bracing needed to prevent sagging, deflection, and uneven surfaces at the seam
- Protects the roof deck long-term - the designed-in 1/8-inch gap accounts for wood movement caused by moisture changes, reducing the likelihood of panel damage that can compromise the integrity of the roof deck over its lifespan
- Fast, no-fastener installation - the clip slides directly over the edges of adjacent panels, making it a quick and practical choice for installers working across large roof sheathing areas
- G90 galvanized finish for outdoor durability - the heavy zinc galvanized coating makes these clips suitable for the demanding outdoor conditions typical of roofing applications, where moisture and weather exposure are ongoing concerns

Frequently Asked Questions
- What is the purpose of a plywood sheathing clip?
- A plywood sheathing clip is inserted over the edges of adjacent plywood panels to brace unsupported sheathing edges where panels meet edge to edge without a rafter beneath the joint. It reduces deflection and keeps panels even to maintain a level plane across the roof deck surface.
- Why is the 1/8-inch gap important in these sheathing clips?
- The 1/8-inch gap built into these clips is specifically designed to address the natural shrinkage and expansion of roof sheathing caused by changes in moisture and temperature. Providing this gap helps prevent panel buckling or warping over time.
- What plywood panel thickness are these clips designed for?
- These Simpson sheathing clips are designed for use with 3/8-inch plywood sheathing panels. Using the correct clip size for the panel thickness ensures a proper, snug fit at the sheathing edges.
- What type of corrosion protection do these clips provide?
- These clips are coated with a zinc galvanized G90 finish, which provides a protective zinc layer that resists corrosion in outdoor roofing environments where exposure to moisture is common.
