OATEY 2114A-1 Dearborn® 1-1/2" x 16" Center To Center, Slip Joint - Budget Ga.

It is the distance between the centerlines of the two vertical legs, which is what has to line up with your existing drain openings. Oatey also builds this trap in a 21 inch center to center version, plus a baffle tee option, so measure your rough-in before ordering rather than assuming the 16 inch will span it.

Yes, a cleanout is included. For a maintenance crew that means the trap can be rodded or drained without pulling the fitting apart, which is the main reason this style gets specified in commercial restrooms and multi-family buildings over a plain trap.

Brass, with a chrome finish. That makes it suitable for exposed applications where the piping is visible under a lavatory or in an ADA-style open-front installation. It weighs 1.97 lbs.

Budget gauge refers to the thinnest wall brass Dearborn offers in this fitting. It handles normal residential and light commercial lavatory service fine, but for high-abuse locations such as schools, correctional facilities, or heavy-traffic public restrooms, buyers generally step up to a heavier gauge version of the same 1-1/2 inch slip joint pattern.

Order the 21 inch center to center version rather than the 2114A-1, which is built at 16 inch. The 2114A-1 part number identifies the 16 inch chrome brass budget gauge configuration specifically, so the center dimension is fixed and cannot be adjusted on site by much.

Installation is slip joint throughout, so you need the slip nuts and washers at each joint and nothing more in the way of adhesive, flux, or solder. A wall escutcheon is typically added separately where the waste arm enters the wall if you want the penetration covered.
