Delaney Solid Brass Surface Bolt

The Delaney Solid Brass Surface Bolt comes in 3 inch and 6 inch lengths, both in the same four finishes. The 3 inch is the common choice for a Dutch door or a cabinet-style opening where the bolt only needs to reach a shallow strike near the meeting edge. The 6 inch gives you more mounting rail on the door face and more reach to the head or the threshold, which is what you generally want on the inactive leaf of a full-height pair of doors. Both are surface applied, so no mortising of the door edge is needed either way.

Not necessarily. The 6 inch figure on the Delaney brass bolt is the length of the bolt assembly on the door face, not the distance it spans up to a header strike. On a tall leaf where the top rail sits well below the frame head, or where you need to bridge a gap at the top of a pair, a longer barrel is the right call. The Ives SB360 heavy-duty steel surface bolt runs 12 inches with a 1-1/4 inch throw for exactly that situation. For a normal-height door with the strike drilled right at the head or the sill, the 6 inch Delaney works.

Plan on new holes. Surface bolts have no standardized screw pattern between manufacturers, so a Delaney 3 inch or 6 inch bolt will not reliably land on the fastener holes left by a different brand. The reason it is still an easy swap is that the door edge is untouched: nothing is mortised, so you are filling a few face screw holes and drilling fresh ones. Check that the new bolt's throw lines up with the existing frame or floor strike hole before you commit, since that hole is the harder one to move.

Use a fire rated bolt. The Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and is fire rated, and the Ives SB1640 is a fire rated brass construction bolt with a 1 inch throw. For a labeled opening in a facility with a 3-hour requirement, the Ives SB1630 is UL listed 3-hour and adds keyed security with a 1 inch throw. The Delaney Solid Brass Surface Bolt is a brass bolt in 3 inch and 6 inch sizes and is specified on standard, non-labeled openings.

The Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, UL listed to 3 hours. The Delaney Solid Brass Surface Bolt is a brass bolt with no key cylinder, sold in 3 inch and 6 inch sizes and in bright brass, satin chrome, satin nickel and satin bronze oil-rubbed. Where a locksmith needs the inactive leaf secured against key control, the SB1630 is the keyed option; where the bolt just holds the leaf and has to match brass trim, the Delaney is the finish match.

The Ives SB360 is a heavy-duty steel surface bolt with a 1-1/4 inch throw offered in a 12 inch length, roughly double the longest Delaney Solid Brass Surface Bolt, which tops out at 6 inches. A longer bar puts the operating handle within reach on a taller leaf without a step stool. The SB360 is steel and fire rated; if the opening needs brass trim to match, the Delaney bolt stays with brass at 3 inch and 6 inch.

Four finishes, all standard BHMA numbers so they cross-reference directly against the rest of your door hardware: 605 bright brass, 613 satin bronze oil-rubbed, 619 satin nickel, and 626 satin chrome. All four are offered in both the 3 inch and 6 inch size, so a property manager standardizing across a building can keep one finish and vary the length by opening.

It's a decorative-grade solid brass bolt, better suited to residential French doors, closet pairs, and light commercial interiors than to a hospital corridor or a school. For heavy duty service ZenSupply carries the ABH HD1805 with a 3/4 inch stainless steel bar, the Ives SB1600 and SB1630 heavy duty steel bolts, and the heavy-duty Ives SB360. On a multi-family or MRO job where the bolt gets thrown daily, specify one of those; the brass Delaney is the right pick when appearance drives the choice.

No handing. A surface bolt mounts flat on the face of the door and slides straight along its own axis, so the same part works on a left hand or right hand leaf, and top or bottom. What you do decide is which face it goes on: the bolt is operated from the side it is mounted, so put it on the secure side of the opening. Order by size and finish only.

The bolt itself mounts to the door face with the screws it ships with, but the bolt has to land in something. At the head you need a strike mortised or a hole drilled into the frame; at the sill you need a floor strike or a drilled hole in the threshold, and a dust-proof floor strike is worth having on an exterior pair so grit doesn't pack the hole. Two bolts per inactive leaf, top and bottom, is the normal configuration on French doors. Match the strike finish to the bolt: 605, 613, 619, or 626.

The Emtek 8511 is the closest cross-brand match ZenSupply carries: a solid brass surface bolt in a 6 inch length, the same construction and the same size as the larger Delaney. The Trimco 4800 Series is another surface bolt line to look at. If you want the same look but need steel instead of brass, the Ives SB1600 and SB360 are the steel options.

Of the comparable bolts, the Ives SB1630 is the keyed one - a heavy duty steel locking surface bolt with a 1 inch throw and keyed security. The ABH HD1805 auto-locks with its 3/4 inch stainless steel bar rather than taking a key. The Delaney Solid Brass Surface Bolt, the Emtek 8511 and the Trimco 4800 Series are hand-operated brass and series bolts without key control. A security integrator who needs the inactive leaf on a key system should be looking at the SB1630.

The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so the bar drops and locks on its own rather than relying on the user to throw it, and the stainless bar resists the wear a brass bar takes in a busy corridor. The Ives SB1600 is another heavy duty steel option, with a 3-1/2 inch throw. The Delaney Solid Brass Surface Bolt is a solid brass bolt in 3 inch and 6 inch sizes and finishes that match brass door trim.

Two families give you a range to standardize across. The Trimco 4800 Series and the ABH HD1805 Series are both series lines of surface bolts, so a facility can specify one series and order across it. The Delaney Solid Brass Surface Bolt runs as a solid brass series in 3 inch and 6 inch sizes and four finishes - 605 bright brass, 626 satin chrome, 619 satin nickel and 613 satin bronze oil-rubbed - which lets a property manager hold one bolt across buildings and change only the finish to match the trim already on the doors.

Throw varies widely across the comparable bolts. The Ives SB1600 throws 3-1/2 inches, the Ives SB360 throws 1-1/4 inches in its 12 inch length, and both the Ives SB1630 and the Ives SB1640 throw 1 inch. Throw is what reaches the strike in the head or the floor, so a deep saddle or a large gap at the head favors the longer throw of the SB1600. Bolt length and throw are separate numbers - the Delaney Solid Brass Surface Bolt is sized by its 3 inch and 6 inch body length.
