Mcguire B8902-CF 1 P-trap 1-1/4 X 1-1/2 Inch

Product Description

The MCGUIRE B8902-CF 1 is a P-trap with set screw designed for drain line connections in residential and light commercial plumbing systems. The set screw provides a secure, adjustable connection that resists pull-out and accidental disassembly once positioned. With a 1-1/4 inch inlet and a 1-1/2 inch outlet, this trap bridges common size transitions found under sinks and lavatory fixtures. Licensed plumbers and experienced service techs install this trap during fixture rough-in, fixture replacement, and drain line repair work.

This P-trap is suited for under-sink drain applications where a 1-1/4 inch fixture tailpiece connects to a 1-1/2 inch branch drain line. Typical install locations include bathroom lavatories, kitchen sinks, and utility sinks in both new construction and remodel scenarios. The set screw design is especially useful in tight cabinet spaces where a positive mechanical lock on the slip joint improves long-term reliability without relying solely on compression alone.

Key Features

• Set screw mechanism secures slip joint connection and prevents unintentional loosening
• 1-1/4 inch inlet to 1-1/2 inch outlet configuration bridges common drain size transitions
• P-trap configuration maintains the water seal required by plumbing codes to block sewer gases
• Compact form factor suited for installation in confined under-sink cabinet spaces

Compatibility

Designed as an OEM-style replacement P-trap for residential and light commercial lavatory and sink drain applications using 1-1/4 inch tailpieces connecting to 1-1/2 inch drain branches.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with the applicable International Plumbing Code (IPC) or local plumbing authority requirements. Shut off the water supply and clear the drain line before beginning work. Verify the trap arm pitch meets code-required slope to the drain branch before tightening the set screw. Do not overtighten the set screw, as doing so may crack the fitting body.
