The Pentair Heater Bolt Down Bracket Kit (460738) is the OEM replacement hold-down bracket kit for MasterTemp pool and spa heaters, securing the heater unit to its mounting surface. IMPORTANT: KIT CONTENTSThis listing is for the complete bolt down bracket kit. Confirm this is the correct item for your installation before ordering. IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIREDGas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification. This bracket kit anchors the MasterTemp heater body securely to its base or pad, preventing movement that could stress gas, electrical, or plumbing connections. Replacing worn or damaged brackets restores proper heater stability and protects surrounding connections from vibration-related wear.

This keeps the heater correctly positioned while connections are tightened, and avoids the need to adjust bracket placement around completed pipework. Verify that all fastener holes align with your pad anchors before committing to final torque.
