Deltana SDL688U3/KNOB – Frequently Asked Questions

1) Can I order just the knob for a Deltana storm door latch, or do I have to buy the whole latch?
The knob is sold on its own, one per unit of measure. So if a tenant snapped a knob off a screen door or you want a different grip style on an SDL688 that's otherwise fine, you replace the knob alone and leave the latch on the door.
2) What finishes does the Deltana SDL688 accessory knob come in?
Nine: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. If you're matching a storm door to existing entry hardware, PVD Polished Brass is the one that holds its color longest outdoors compared with standard lacquered polished brass.
3) How far does the Deltana storm door knob stick out from the door?
Projection is 1-5/8 inches. That matters on a storm or screen door because the knob sits outboard of the main entry door and can foul the main door's hardware, a closer arm, or a screen frame if clearance is tight. Diameter is also 1-5/8 inches, so it's a compact ball-style grip rather than a full entry knob.
4) Is the Deltana SDL688 knob solid brass or brass plated?
Solid brass through the body, not a plated pot metal core. Both the material and the substrate are brass, so the finish sits on brass. On an exterior storm door that's the difference between a knob that patinas and one that flakes and corrodes at the set screw.
5) Is this Deltana knob rated for commercial storm doors on an apartment building?
It's a residential-duty part. For a single-family door, a duplex, or a low-traffic unit entry it's the right piece. On a high-traffic commercial or common-area opening, spec commercial-grade hardware instead of a residential storm door latch knob.
6) Do I need a knob or a lever for the Deltana SDL688 storm door latch?
This part is the knob version. It's a round grip you turn, which suits a storm door where a lever can snag clothing or catch on the main door swing. If the opening needs to be operated with a closed fist or a forearm, a knob is the wrong choice and you want a lever-style accessory for the same latch.
