Manufactured from true marine-grade 316 stainless steel, this in-pool umbrella sleeve is built for full-time submersion.

Stainless Steel Pool Sleeve

This stainless steel pool sleeve is designed for underwater use where plastic inserts fail. It will not crack, deform, or loosen over time, even in saltwater pools, high-chlorine systems, or fully submerged Baja shelf installations.

Baja Shelf Umbrella Sleeve

As a dedicated baja shelf umbrella sleeve, this product provides straight, centered umbrella alignment on shallow tanning ledges. It eliminates leaning umbrellas and long-term movement common with builder-grade sleeves.

In-Pool Umbrella Sleeve

This in-pool umbrella sleeve supports daily umbrella use while remaining fully submerged. The marine-grade steel construction prevents corrosion, wobble, and structural breakdown over time.

Sun Ledge Umbrella Sleeve

For shallow pool ledges, this sun ledge umbrella sleeve installs flush with plaster, PebbleTec, or PebbleSheen finishes while maintaining a clean, professional appearance.

Rustproof Umbrella Sleeve

Built from marine-grade 316 stainless steel, this rustproof umbrella sleeve prevents rust staining, pitting, and metal degradation caused by constant exposure to water and pool chemicals.

Precision Fit for Stable Umbrella Support

The internal chamber measures 6″ deep × 1.47″ wide, matching common builder standards. This allows compatibility with BajaMate adapters which then supports 1.5″–2.05″ umbrella poles using reducer rings—without wobble or shifting.

Included Leveling Tool for Straight Installs

Every 316 Stainless Steel In-Pool Umbrella Sleeve includes the patented BajaMate Leveling Tool, allowing installers to set the sleeve perfectly vertical before placement. This ensures straight umbrellas and a clean, professional install.

Threadless Cap with Debris Seal

A smooth, threadless cap with an integrated gasket seals the sleeve when not in use. It prevents debris intrusion and blends seamlessly into plaster and pebble finishes. Caps are available in Steel finish.
