What it does

Supports the housing and supplies the primary mounting hardware

The housing head bolts to the horizontal bracket plate, while the bracket fastens to a wall, mounting board, or other suitable structural surface. This transfers the weight of the filled housing away from the inlet and outlet plumbing and helps keep the filter vertical and stable.

Before purchase

Good to know

!
Wall anchors are not included
Masonry, block, brick, and hollow-wall installations require suitable anchors selected for the substrate and load.

!
Not for slim housings
This bracket does not fit standard 10″ × 2.5″ slim housing heads.

!
Single-stage bracket only
Use a dual or triple Big Blue bracket for systems with two or three housings.

!
Verify the housing-head pattern
Big Blue-style housings from different manufacturers may use different mounting-hole spacing.

!
Plan for the filled-system weight
A water-filled Big Blue housing may weigh approximately 12–20 lb or more, particularly in a 20″ configuration.

!
Indoor or protected installation
The bracket and supplied hardware should not be exposed continuously to rain, salt spray, or severe outdoor conditions.

This product includes one bracket and eight screws. Filter housing, cartridge, wall anchors, valves, nipples, plumbing fittings and installation tools are not included. Verify the housing-head mounting pattern, wall construction, required anchors and complete water-filled system weight before installation.
