Deltana HPR35 Stainless Steel Pin for 3-1/2" Solid Brass Hinges (DSB35 Series)

The HPR35 is the barrel pin for Deltana's DSB35 series, which is their 3-1/2 inch solid brass hinge. It measures 2-3/4 inches long by 1/4 inch diameter. If your hinge is a Deltana 3-1/2 inch solid brass unit, this is the matching pin. A 3-1/2 inch hinge from another maker may use a different barrel length or pin diameter, so measure the old pin against those two numbers before ordering.

The pin itself is stainless steel, offered in a brushed stainless finish, even though it goes into a solid brass hinge. That's a deliberate pairing: the stainless barrel carries the door load and resists corrosion while the brass leaves carry the decorative finish. Once installed only the pin head and the knuckle ends show, so if you're matching a polished or antique brass hinge exactly, expect the pin to read as a slightly different tone.

One pin per hinge. The HPR35 is sold each, so a door on three 3-1/2 inch DSB35 hinges takes three pins, and a lighter door on two hinges takes two. Property managers doing a building sweep should count hinges, not doors.

Deltana classes the HPR35 as residential hardware, matched to the DSB35 solid brass residential hinge line. It's the right pin for apartment, condo, and single-family interior and entry doors. For a high-traffic commercial opening, a stairwell, or anything on a fire-rated assembly, you want a full commercial-grade hinge rather than a replacement pin for a residential one.

Plain barrel pin. The HPR35 is the functional stainless replacement pin, 1/4 inch diameter and 2-3/4 inches long, not a ball-tip, urn, or steeple finial pin. If you're after a decorative tip on a 3-1/2 inch brass hinge, you need a finial-style pin, not this one.
