U.S. Pool Supply Wide-Mouth Thru-Wall Above-Ground Pool Skimmer Kit — Wide Opening, UV-Resistant ABS

The U.S. Pool Supply Wide Mouth Thru-Wall Skimmer Kit is a heavy-duty, permanent replacement skimmer that fits most above-ground pools and removes surface debris more effectively than over-the-wall models.

Replace a worn or temporary skimmer with a professional-grade, wide-mouth thru-wall unit designed for long life and reliable surface skimming. Built from UV-resistant ABS plastic and complete with stainless-steel hardware, double gaskets, a weighted weir door, and a vacuum plate adapter, this kit is engineered to restore proper skimming performance and keep pool water clearer with less strain on your pump. It’s made as a direct-style replacement for common models such as the Hayward SP1091WM and works with most steel-walled above-ground pools.

How does this skimmer improve debris removal?

The wider throat and weighted weir door create a stronger surface draw that captures leaves, insects, and other floating debris before they sink. That early removal prevents debris from reaching the main filter and reduces how often you need deep cleaning.

• Wide mouth opening allows larger debris entry.
• Weighted snap-in weir door maintains continuous surface suction.
• High-efficiency debris basket keeps solids contained and easy to empty.

What does the kit include and why does it matter?

This is a complete installation package so you won’t need extra parts or specialty tools for a standard replace-in-wall job. All components are selected to resist pool chemicals and outdoor exposure for extended service life.

• Skimmer housing, housing support, faceplate, and cover for a secure thru-wall fit.
• Double gaskets and twelve stainless-steel screws to form a long-lasting, leak-resistant seal.
• Debris basket, vacuum plate, and hose adapter for routine vacuuming and maintenance.

Is this kit compatible with my above-ground pool and hoses?

The skimmer is designed to fit most major above-ground brands and commonly replaces popular units like the Hayward SP1091WM. The included vacuum plate adapter accepts standard 1 1/4" and 1 1/2" vacuum hoses used with pressure or suction vacuums.

• Outer dimensions: 14 1/4" x 7 7/8"; inner opening: 11 1/2" x 5" for sizing checks.
• Works with standard 1 1/4" and 1 1/2" vacuum hose fittings via included adaptor.
• Primarily intended for steel-walled above-ground pools; liner modifications needed for soft-sided pools.

How difficult is installation and what tools will I need?

Installation is suitable for experienced DIYers and pool owners comfortable with cutting a thru-wall opening in steel pool walls. The kit supplies all fasteners and gaskets; typical installations require basic hand tools and careful measurement.

• Includes stainless hardware and double gaskets to simplify sealing and attachment.
• Requires measuring, cutting the outer pool wall, and securing housing from both sides.
• If unsure, a single-session pro install is an option to ensure watertight fitment.

Who is this for? Pool owners with steel-walled above-ground pools who want a permanent, higher-performing skimming solution instead of temporary over-the-wall or floating units. It’s ideal for anyone replacing an old thru-wall skimmer—especially Hayward SP1091WM-style models—who prefers a robust, UV-resistant assembly that includes vacuum and hose fittings for routine maintenance without extra purchases.
