West Systems 731 Fiberglass Reinforcing Tape 3" x 50 Yards 9 oz

The West System 731 is a versatile 9 oz. fiberglass cloth tape designed specifically for structural reinforcement applications in boat building and repair. This professional-grade tape measures 3 inches wide by 50 yards long and is sold in cases of 4 rolls.

Key Features:

• 9 oz. per square yard fiberglass cloth construction for optimal strength-to-weight ratio
• 3-inch width ideal for reinforcing chines, hull-deck joints, and structural corners
• 50 yard length per roll provides excellent coverage for large projects
• Designed to bond with WEST SYSTEM epoxy resins for maximum adhesion
• Provides exceptional tensile strength to resist stress cracking and joint failure
• Adds abrasion resistance to high-wear areas
• Conforms easily to curved surfaces and complex geometries

When saturated with WEST SYSTEM epoxy, this fiberglass tape creates a strong, durable composite laminate that reinforces critical joints and stress points. The 9 oz. weight strikes an excellent balance between conformability and structural strength, making it easier to wet out than heavier fabrics while still providing robust reinforcement. Ideal for marine applications including wooden boat construction, fiberglass repairs, composite fabrication, and general structural bonding where additional tensile strength is required.
