Provide reinforcement at critical load points to prevent web crippling
(QTWS) EasyClip™ Quick Twist Web Stiffeners are used to provide reinforcement of joist webs to prevent crippling.
Web reinforcement is often required by design to enhance the load capacity of joists. The unique design of this web stiffener allows the installer to insert the stiffener on the inside of the joist after the joist is installed. This stiffener eliminates the need to pre-insert traditional web stiffeners prior to joist installation. The one-piece assembly is easily rotated in-place for a tight fit.
- Simple, post installation assembly
- Easily rotated in-place for a tight fit
- Pre-punched for easy installation of fasteners
- Solid 12 gauge construction
- One-piece assembly
