Rockwood 630 Surface Bolts

Two bolt lengths: 8 inches and 24 inches. The 8 inch is the usual choice for a bolt mounted at the top or bottom rail of an inactive leaf within easy reach. The 24 inch is what you use when you need to throw a bolt into the head of a tall opening from a height a person can actually reach, or when you want the bolt to span more of the stile for appearance on a pair of doors.

Both strikes ship with it. The 630 is supplied with a universal strike and a mortise strike, so you can either surface-apply the strike to the frame or floor, or mortise it in for a flush finish. Mounting screws are included too: 12 each #6 x 3/4 inch oval head sheet metal screws.

The Rockwood 630 is a solid brass surface bolt supplied with universal and mortise strikes, offered in 8 inch and 24 inch bolt lengths. If the opening requires a fire rated bolt, the Ives SB1640 is a fire rated brass surface bolt with a 1 inch throw, and the Ives SB1600 is a heavy duty steel fire rated surface bolt with a 3-1/2 inch throw. For a listed hourly rating, the Ives SB1630 is a heavy duty steel locking surface bolt carrying a 3-hour UL listing.

The Rockwood 630 is a solid brass bolt catalogued for residential use. For heavier openings, the Ives SB1600 and SB1630 are heavy duty steel surface bolts, and the Ives SB360 is a heavy-duty steel bolt with a 1-1/4 inch throw in a 12 inch length. The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar if you want the bolt to latch itself when thrown.

Solid brass construction, supplied in UD26D. The solid brass body matters on an inactive leaf that gets handled daily, and it also means the bolt takes a plated finish rather than a painted one.

No. The 630 uses a fiber gasket that puts friction on the bolt so it stays where you set it, and the gasket does it without marring the bolt's finish as it slides. That's the difference between this and a plain slide bolt that creeps open under door movement or vibration.

The Emtek 8511 is a solid brass surface bolt in a 6 inch length, shorter than either Rockwood 630 size. Delaney also offers a solid brass surface bolt and a decorative solid brass version if appearance drives the choice. All of those are brass like the 630; if you'd rather have steel, the Ives SB360 is a heavy duty steel bolt with a 1-1/4 inch throw in a 12 inch length.

That's its normal job. A surface bolt mounts on the face of the inactive leaf and throws into a strike at the head or the floor, holding that leaf fixed so the active leaf can latch against it. Because both a universal and a mortise strike come in the box, you can catch it into the frame head or into a floor strike depending on how the pair is built.

It's a slide bolt, held in position by the fiber gasket friction rather than by a key. If you need the bolt itself keyed so it can't be retracted by anyone who can reach it, the Ives SB1630 is a heavy duty locking surface bolt with keyed security and a 1 inch throw.

No. The Rockwood 630 is a manual surface bolt operated by a 1 inch diameter knob, with no keyed provision. If the inactive leaf has to be secured against key control, the Ives SB1630 is a heavy duty steel locking surface bolt with keyed security and a 1 inch throw.

The Trimco 4800 Series is a surface bolt line and serves the same purpose of holding an inactive leaf, but it is a different series with its own strike and fastener package. The Rockwood 630 ships with 12 each #6 x 3/4 inch oval head sheet metal screws plus both a universal and a mortise strike, so if you are matching existing 630 bolts on other doors, staying with the 630 keeps the strike prep and screw pattern identical across the fleet.
