Deltana DSBU3 Solid Brass Finial - Button Tip (For 3" x 3" Hinges)

The DSBU3 button tip is made for Deltana 3 x 3 inch solid brass hinges. It threads onto the hinge pin with an 8 x 1.25mm thread, so it is not a friction-fit cap and won't seat on a hinge that isn't cut for that thread. If your hinges are a larger Deltana size, this is the wrong tip for them.

Yes, if the hinges are Deltana 3 x 3 solid brass. The finials thread on and off at 8 x 1.25mm, so the tips swap on the pin while the hinge leaves stay screwed to the door and frame. For a property manager restyling a run of openings, that means the finish change happens without removing a single door.

Very little. The button tip stands 1/8 inch tall and measures 1/2 inch in diameter, so it sits close to the barrel rather than extending it the way a ball or steeple tip does. That matters if the hinge is close to a stop, casing, or crown detail where a taller decorative tip would foul.

Eleven finishes: Polished Brass, Unlacquered Brass, Brushed Brass, Antique Brass, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, Oil Rubbed Bronze, and Paint Black. Match the tip finish to the hinge you already have rather than to the lockset, since the tip sits on the hinge barrel and any mismatch reads at eye level.

Priced and sold each. A hinge takes two tips, one top and one bottom, so a single 3 x 3 hinge needs two DSBU3 finials and a standard three-hinge door needs six. Count the openings before you order or you will be a tip short on the last door.

No. The button tip is a decorative finial and does not add NRP security; the pin still comes out. If you need a pin that cannot be pulled from the hinge side on an outswing exterior door, specify a hinge with the non-removable pin feature rather than relying on the tip.

A button tip is the low, flat-crowned cap, standing 1/8 inch at 1/2 inch diameter. Ball and steeple tips are taller and more ornamental. Button is the choice when you want the hinge to read as plain hardware, or where trim sits close to the barrel; a ball or steeple tip is the one to pick when the hinge is meant to be a period detail. All of them thread onto the same Deltana 3 x 3 pin, so the decision is purely appearance.

The DSBU3 is solid brass through the body, not plated pot metal, and Deltana classes it for commercial use. Since it is a decorative cap on the hinge pin and carries no door load, the practical wear question is the finish, not the metal. Unlacquered brass will patina in a lobby; the plated and painted finishes hold their look longer under cleaning.
