Hayward Retainer Clamp for AstroLite SP0580 Underwater Light — Replacement Kit with Screw, Nut & Washer

Hayward SPX0580B is a direct-fit retainer clamp assembly engineered to secure the SP0580 AstroLite series underwater light, supplied with screw, nut and washer for straightforward replacement.

If your pool or spa light housing needs a reliable clamp to hold the AstroLite SP0580 lamp in place, this OEM-style retainer clamp restores the fixture’s mechanical integrity without requiring a full light replacement. The kit contains the metal clamp and the fasteners you need for reassembly — a compact repair part intended for service or maintenance of Hayward SP0580 underwater lighting.

How does this clamp restore my underwater light?

The retainer clamp replaces the original fastening hardware that locks the SP0580 lamp into its housing. By installing the included screw, nut and washer, the clamp re-establishes the correct tension and alignment so the lamp sits firmly and resists movement.

• Direct-fit for Hayward AstroLite SP0580 housings
• Includes matching screw, nut and washer for immediate installation
• Replaces worn or corroded retaining hardware without changing the light

What parts are included and what materials should I expect?

The replacement kit contains a single retainer clamp plus one screw, one nut and one washer. While Hayward designs these components for pool use, expect typical metal hardware treated for corrosion resistance; always inspect parts for compatibility before installing.

• One retainer clamp shaped for SP0580 AstroLite lights
• One screw, nut and washer sized for the clamp assembly
• Packaged as a ready-to-install service part, weighing about 5.7 pounds

Is this easy to install and what tools are required?

Installation is straightforward for anyone comfortable with basic pool-light maintenance. You’ll need simple hand tools to remove the old clamp and fasten the replacement; follow safety guidance to keep electrical components dry and disconnected before you begin.

• Requires basic hand tools (screwdriver and wrench)
• Disconnect power to the light before servicing
• Fits directly into the existing SP0580 light housing with included hardware

Will this fit other Hayward lights or universal housings?

This retainer clamp is manufactured specifically for the Hayward AstroLite SP0580 underwater light model. While some users adapt parts across similar housings, guaranteed fitment and optimal performance are achieved when used with the SP0580 series.

• OEM-fit for SP0580 AstroLite series only
• Not recommended as a universal clamp substitute
• Check model numbers before ordering to ensure compatibility

Who is this for: Pool professionals, maintenance technicians and DIY owners who need a direct replacement retainer clamp for a Hayward SP0580 AstroLite underwater light. If you own an SP0580 fixture and have a corroded, missing or damaged clamp, this part brings back the mechanical function without replacing the entire light assembly.
