Emtek 2620 Solid Brass Door Knocker, Urn Style

Surface mount. The 2620 urn knocker fastens to the face of the door, so there is no bore or through-cut for the knocker body itself, unlike a knocker-viewer combination that requires a viewer hole. That makes it the easier retrofit on an existing slab or on a door you do not want to cut.

Emtek lists the 2620 as residential. For a house, townhome, or the unit doors in a multi-family building where the look matters, it fits. For a high-traffic commercial main entrance, or anywhere the door hardware has to be spec'd to a commercial grade, look at a commercial line instead: ZenSupply carries the Trimco 620 Series contemporary knocker and the Trimco 621 Series colonial knocker for that side of the market.

No viewer on the 2620. It is a plain urn style knocker, surface mounted, with no peephole in the body. If you want the knocker and the viewer as one unit, the Trimco 620 Series is a contemporary style knocker offered with an optional viewer, and it can be engraved. Going with the 2620 means drilling and installing a separate door viewer if you want one.

The Emtek 2620 is a residential door knocker. The Trimco 620 and 621 are the alternatives to price when the specification is being written for a commercial entrance, with the 620 in a contemporary face and the 621 in a colonial face.

Solid brass is the substrate on the 2620, not a plating over zinc or steel. That matters on an exterior door: the finish wears into more brass rather than exposing a different base metal underneath. The unlacquered brass version (US3NL) is the one that will patina with exposure; the polished brass, satin nickel, oil rubbed bronze and flat black versions are finished over the same brass body.

Five finishes cover the 2620 urn knocker: Oil Rubbed Bronze (US10B), Satin Nickel (US15), Flat Black (US19), Polished Brass Lifetime (US3), and Unlacquered Brass (US3NL). Those are standard US finish codes, so if the entry set on the door is already spec'd US10B or US15 the knocker will read as the same family. Order by the model plus finish code, for example 2620US15 for satin nickel. If you want a knocker that will darken and age naturally rather than hold its color, US3NL is the unlacquered option; US3 is the lifetime-coated polished brass that stays bright.

Style is the whole decision here, since all three are surface mounted knockers doing the same job. The Emtek 2620 is an urn shape in the American Classic vein, which sits well on a paneled traditional or colonial-era door alongside a knob or handleset in the same finish. If you want something plainer and more modern, the Trimco 620 is contemporary styled. The Trimco 621 is explicitly colonial styled, which is the closer match if the rest of the door is doing a strict period look rather than a general traditional one.

No. The Trimco 621 is a colonial style door knocker from the 621 Series. The Emtek 2620 is an urn style knocker in solid brass with an American Classic theme. They are both surface mount entry door knockers, but the 621 is a different maker's series and a different face design, so it is not a drop-in match for an existing 2620 on a neighboring door.

The Trimco 620 is the knocker offered with optional engraving. The Emtek 2620 is a plain urn style solid brass knocker with no engraving option, so an entry that needs a unit number or name on the knocker itself points to the 620.

Yes, and the finish code is what keeps it consistent. Each finish is its own part number off the 2620 body: 2620US10B for oil rubbed bronze, 2620US19 for flat black, 2620US3 for polished brass. Ordering one code across the fleet means every door gets an identical solid brass knocker rather than a near-match. Since it is surface mounted, the install is the same on every door with no bore work, which is what makes it practical to roll out across a building.

Purely mechanical. The 2620 is a brass urn knocker with no electronics, no chime, and no wiring. If the requirement is an audible signal inside the house, that is a separate doorbell or chime; the knocker is struck by hand against the strike plate on its own body.
