Simpson Plywood Sheathing Clip - 1/2 Inch Panel Thickness by Simpson is an essential structural connector engineered to brace unsupported sheathing edges where roof panels meet edge to edge without the benefit of a rafter for support. Fabricated in the United States from 20-gauge steel with a zinc galvanized G90 finish, this plywood panel clip is designed to reduce deflection, maintain panel alignment, and create a level roof plane - giving contractors and builders a reliable solution for code-compliant roof sheathing installation.

Key Features

• Designed for 1/2-inch panel thickness - fits precisely over the edges of adjacent 1/2-inch plywood sheathing panels, ensuring a secure, flush connection without guesswork
• Provides a built-in 1/8-inch gap - accommodates natural shrinkage and expansion of roof sheathing over time, reducing the risk of buckling or warping as panels move with seasonal moisture changes
• Reduces panel deflection - keeps adjacent plywood panels even and flush, maintaining a consistent level plane on the roof structure for a smooth, professional finish
• 20-gauge steel construction - delivers reliable structural performance while keeping the clip lightweight and easy to handle during installation
• Zinc galvanized G90 coating - provides corrosion resistance suited for outdoor roofing applications and exposure to the elements
• Made in the United States - manufactured to consistent quality standards for dependable structural performance

Why This Product

• Solves the unsupported edge problem - when roof sheathing panels meet edge to edge without a rafter underneath, this clip bridges that gap and prevents panel movement, which is critical for long-term roof integrity
• Built-in expansion gap prevents damage - the engineered 1/8-inch spacing accounts for wood expansion and contraction, reducing the likelihood of sheathing buckles or structural stress at panel joints
• Keeps the roof surface level - by minimizing deflection between adjacent panels, this clip helps create an even substrate for roofing materials, improving both appearance and performance of the finished roof
• Lightweight and field-friendly - the 20-gauge profile is easy to insert over panel edges during installation without adding unnecessary bulk or complexity to the sheathing process

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 without a rafter beneath them. It reduces deflection between panels and keeps them even to maintain a level plane on the roof structure.

Why does this clip include a 1/8-inch gap?

The built-in 1/8-inch gap is engineered to address the natural shrinkage and expansion of roof sheathing as wood responds to changes in moisture and temperature. This spacing helps prevent buckling and structural stress at panel joints over time.

How do I select the correct sheathing clip size?

Match the sheathing clip size to the panel thickness. This clip is sized specifically for 1/2-inch plywood sheathing panels. Using the correct size ensures a proper fit over panel edges and the intended structural performance.

Are there any installation considerations for low slopes or heavy loads?

Yes - maximum spans may be reduced for low slopes or high uniform loads. Always refer to the sheathing manufacturer's installation instructions for guidance specific to your project conditions.
