Storm Door Latch, Classic, Mortise Lock

These mortise door latches, unlike a tubular latch style door latch, give you that crisp feel of a secure, solid, tight fit when closed. That nice "click" that let's you know the fitment is perfect.

Mortise latches are also very durable, which makes them the best for heavy use, perfect for a front or rear door on your home. Without sacrificing style.

This is a Solid Brass construction mortise lockset for screen doors, patio doors and storm doors. It has a door lever and thumb turn lock on the inside, and a door knob on the outside.

  • 1-1/2" Backset
  • 7/8"- 1-3/4" Door Thickness range
  • 6"x 1-1/2" Extruded brass escutcheon back plates
  • 3-1/4"x 3/4" Face Size
  • Reversible Handing
  • 1-3/4" solid brass knob projection
  • 2" solid brass lever projection

Deltana SDL688U3 – Frequently Asked Questions

1) Is the Deltana SDL688 storm door latch handed, or does it work on a left and right hand door?
Handing is reversible on the SDL688, so one part number covers a left or right hand storm door. That matters if you are buying for several openings at once and do not want to sort handing per door.
2) What do you get on the inside versus the outside of the door with the Deltana SDL688?
Outside is a knob, inside is a lever with a thumb turn for locking. So you pull the door shut by the knob from outside and throw the thumb turn from inside. There is no key cylinder in the set, it is a thumb turn lock only. Both sides mount on 6 x 1-1/2 inch extruded brass escutcheon back plates.
3) My existing storm door latch has a 1-1/2 inch backset, will the Deltana SDL688 drop into that prep?
Backset on the SDL688 is 1-1/2 inches, which is the common storm and screen door backset, so if your current latch measures 1-1/2 inches from the door edge to the handle center, the handle holes line up. The mortise pocket is the part to check, the face plate is 3-1/4 x 3/4 inches, and the escutcheon plates are 6 x 1-1/2 inches, which will cover a fair amount of old fastener holes on the door face. If your current latch is a tubular type in a bored hole rather than a mortise pocket, this is not a drop in, the edge has to be mortised.
4) What finishes does the Deltana SDL688 storm door latch come in?
Nine finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. If you are matching a run of units, PVD Polished Brass is the one to pick for exterior exposure over standard polished brass, since PVD is a plated coating rather than a lacquered brass surface.
5) How far does the Deltana SDL688 knob stick out from the door?
Projection is 1-3/4 inches on the solid brass knob side and 2 inches on the lever side. Worth checking against your main entry door swing, since a storm door handle that projects 2 inches can foul an entry door lever or a storm door closer arm when the two doors are close together.
6) Mortise or tubular latch for a storm door, which should I use?
A mortise latch like the SDL688 sits in a pocket cut into the door edge rather than a bored hole, and it closes with a tighter, more solid feel. Deltana positions the mortise style as the more durable choice for heavy use doors, front and rear entries that get cycled constantly. A tubular latch is the simpler install if the door is already bored for one. If you are cutting fresh, the mortise pocket is more work up front but is the harder wearing latch.
7) Is the Deltana SDL688 solid brass or plated pot metal?
Solid brass through the lockset, including the knob and the extruded brass escutcheon plates. On a storm door that lives in the weather, that is the difference between a handle that holds up and one that pits.
8) Can I use the Deltana SDL688 on a commercial building entrance?
Deltana classes the SDL688 as residential hardware. It is built for screen, patio and storm doors on homes. For a commercial opening that needs a graded, cycle rated lock, this is not the part, look at a commercial mortise lockset instead.
