4 oz 30" E-Glass (Full Roll)

The Shaper Supply 4 oz 30" E-Glass fiberglass full roll is a high-quality cloth designed for surfboard production and trusted by leading surfboard manufacturers in the US. Each full roll contains 109 yards of premium fiberglass cloth, providing an economical option for production glass shops, builders, and anyone using fiberglass regularly.

This ultra-white E-Glass cloth features a soft drape that conforms easily around rails and contours. It wets out cleanly with both epoxy and polyester resins, producing a clear laminate with excellent tensile strength and clean, clear laps.

The 30-inch width provides additional coverage compared to standard 27-inch cloth, making it a popular choice for wider shortboards, mid-lengths, and other designs where extra rail overlap is desired. This added width helps achieve consistent laps while reducing the need for additional material during lamination.

The 4 oz weight offers an excellent balance of strength, weight, and flexibility, making it one of the most commonly used fiberglass cloths in modern surfboard construction.
