GLI ProMesh — Nearly 100% Sunlight Blockage, No Pump Needed.

ProMesh is made from a unique polypropylene-extruded double-layer weave mesh: 6.5 oz. per square yard, nearly 50% lighter than solid covers, with nearly 100% sunlight blockage and nearly 75% more tensile strength than standard mesh for greater tear strength, abrasion resistance and burst strength. It lets water through for drainage and safety while keeping sunlight and debris out, so you open to cleaner water in the spring — no cover pump needed. Meets or exceeds ASTM F 1346-91. 20-year limited warranty with 5 years of full coverage.

Sized for a rectangular in-ground pool with 2' offset step, 20 x 40, right-hand step. Available in Green, Blue, Gray or Tan — same price in every color; the photo for each color shows the GLI ProMesh cover in that color on a sample pool (the pool shape in the photo may differ from this size).

Left or right step? GLI determines the step side by standing in the deep end of the pool and looking toward the shallow end. Some other cover brands measure it from the opposite end, so if you are replacing another brand’s cover please confirm the side using GLI’s method before ordering — a left-hand cover will not fit a right-hand pool.
