Deltana DGSB675 Door Guard, 6-3/4"

The DGSB675 is a swing-bar style door guard that lets an entry door open only partway so you can see and speak to whoever is outside before releasing it. It is not a lock and does not replace one. Think of it as the secondary restraint you add above or below the deadbolt on an apartment, hotel, or office entry door.

The bar has an extended length of 6-3/4 inches, so that is roughly the gap you get at the door edge when the guard is engaged. Wide enough to pass a clipboard, a key, or a package receipt through, and to talk face to face, but not to admit a person. If you need a longer opening than that, the 6-3/4 inch size is the wrong one to order.

Solid brass throughout, both the bar and the mounting components. That matters on a swing bar because the bar is what takes the hit if someone shoves the door, and a cast zinc bar is where cheap guards fail. Brass also means the finish is applied over a substrate that will not blister the way plated white metal does in a humid corridor or a coastal building.

Nine finishes: polished brass, PVD polished brass, antique brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, brushed chrome, and painted black. If the building's levers are oil rubbed bronze, order the guard in oil rubbed bronze. Worth knowing the difference between the two brass options: PVD polished brass is a vacuum-deposited coating that holds up to handling and cleaning far better than standard lacquered polished brass, which is the one that wears through first on a door people touch every day.

Deltana lists the DGSB675 as commercial. That is the relevant distinction for a multi-family or hospitality buyer specifying a secondary restraint across a floor of units rather than buying one for a house.

A rigid brass swing bar like the DGSB675 is the stronger of the two. A chain has links and a slotted keeper, and both are common failure points under a kick. The swing bar is a single piece of solid brass, .48 wide, pivoting on a mounted post, so there is no link to break. Chains do have one advantage: they can be released from outside more easily by maintenance, which is exactly why security-minded buyers avoid them. Choose the bar for entry doors where you want the occupant in control; choose a chain only where you want an easier override.

Sold each, one guard per unit, and one guard is what a single door needs. If you are outfitting 40 apartment entries, that is a quantity of 40. Price shown is per unit, not per pair or per box.
