Rockwood 585-12 US26D – Frequently Asked Questions
1) What bolt lengths does the Rockwood 585 come in, and which one do I need?
Two lengths: 12 inch and 24 inch. The length is the bolt bar itself, not the throw. Pick by how far up the door face you need to reach from the operating knob to the top of the door (a 24 inch bar gets the hand closer to eye level on a standard opening, a 12 inch bar keeps the hardware low and tight). Both are the same steel bolt with a 1-1/4 inch throw.
2) How far does the Rockwood 585 bolt throw, and will it reach into a floor strike?
Throw is 1-1/4 inches on 3/4 by 3/4 inch solid bolt material. A mortise bottom strike is included, so the floor side is prepped for the bolt as supplied. The 1-1/4 inch projection is what has to clear your threshold or floor covering, so measure from the bottom of the door to the finished floor before you commit.
3) Do I need to buy strikes separately with the Rockwood 585 surface bolt?
No, both strikes ship with it. A universal top strike and a mortise bottom strike are included. Fasteners come in the box too: for the bolt, four 1/4-20 x 2-1/4 inch flat head machine screws and four 1/4-20 x 1-5/8 inch sex bolts; for the strikes, two #14 x 2-1/2 inch flat head sheet metal screws with two plastic anchors, plus two 1/4-20 x 1 inch flat head machine screws with two 1/4-20 anchors. The sex bolts are what let you through-bolt the bolt body on a hollow metal or wood door.
4) Does the Rockwood 585 stay locked in the open position so the inactive leaf can swing free?
It locks in both the up and the down position. Thrown, the bolt locks automatically and can only be released by pressing the knob toward the door while you retract it. Retracted, it stays retracted, so the leaf will not drop a bolt on you while you are moving stock or furniture through a full pair opening. For a property manager running a service corridor, that is the behavior that stops the bolt from being wedged or taped.
5) I need a longer throw than 1-1/4 inches to clear a raised threshold. What surface bolt should I look at?
The 585's throw is fixed at 1-1/4 inches, so a deep threshold or a thick floor covering can eat it. The Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and is fire rated, which is the one to move to when you need real projection at the sill.
6) What is the closest equivalent to the Rockwood 585 surface bolt for an inactive leaf on a pair of 3-hour labeled fire doors?
The Rockwood 585 is a steel surface bolt with a 1-1/4 inch throw, UL listed for use on the inactive leaf of a pair of 3-hour labeled fire doors, and it comes in 12 inch and 24 inch bolt lengths. The nearest match by throw is the Ives SB360 heavy-duty steel surface bolt, which also carries a 1-1/4 inch throw in a 12 inch length and is fire rated. For a keyed version at that fire label, the Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and a 3-hour UL listing, so it trades throw depth for keyed security.
7) I need more bolt engagement than a 1-1/4 inch throw gives me at the head of the door. What surface bolt should I use instead of the Rockwood 585?
The Rockwood 585 throws 1-1/4 inches with 3/4 inch by 3/4 inch bolt material. When the frame condition or an undercut header calls for deeper engagement, the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and is fire rated, which is the longest throw among the steel heavy duty bolts in the comparable range. Confirm your strike prep can accept the longer bolt before specifying it, since the 585 ships with a universal top strike and a mortise bottom strike sized to its own 1-1/4 inch throw.
8) Will a Rockwood 585 surface bolt work on a hollow metal door, or only on wood?
Any door type. The 585 is a surface applied steel bolt, so nothing is mortised into the door itself, and the included fastener pack covers both cases: sex bolts to through-bolt where you can get both faces, machine screws where you are tapping into metal. Only the bottom strike requires a mortise, and that is into the floor, not the door.
9) Can you padlock a Rockwood 585 surface bolt for after-hours security?
Yes, the 585 accommodates a padlock. Common on stockroom and dock pairs where the inactive leaf gets bolted and then padlocked overnight. If you want key control built into the bolt instead of a separate padlock, the Ives SB1630 is a keyed locking surface bolt, though its throw is 1 inch rather than the 585's 1-1/4 inch.
10) Do I need a surface bolt or a flush bolt on the inactive leaf of my pair?
Surface bolts like the Rockwood 585 mount on the door face, so there is no mortising of the door and they can go on an existing pair without machining, including retrofits where the leaf is already hung. Flush bolts are let into the door edge and disappear from view, which is what you want on a public-facing opening, but they require prep and are usually specified at door manufacture. On labeled pairs the 585 is UL listed for the inactive leaf of 3-hour doors, so a surface application is not a compromise on the rating.
11) Is the Rockwood 585 handed? Do I have to specify left or right?
No handing to specify. The 585 mounts to the face of the inactive leaf and comes with a universal top strike, so the same bolt works on either leaf of a pair regardless of swing. You only choose the bar length, 12 inch or 24 inch.
12) What is the difference between the Rockwood 585 and the ABH HD1805 surface bolt?
Both are auto-locking heavy duty surface bolts with 3/4 inch bolt bar stock. The Rockwood 585 is steel with 3/4 inch by 3/4 inch bolt material, locks in both the up and down position, locks automatically when thrown and releases only by pressing the knob toward the door while retracting, and accommodates a padlock. The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, so the bar material is the main separator when the opening is exterior or corrosive.
13) The spec calls for a Trimco 4800 surface bolt. What is the Rockwood cross?
The Rockwood cross to the Trimco 4800 Series surface bolt is the Rockwood 585, a steel commercial surface bolt built to ANSI A156.16, L04161 with a 1-1/4 inch throw, offered in 12 inch and 24 inch bolt lengths and UL listed for the inactive leaf of a pair of 3-hour labeled fire doors. Match the bolt length called out on the drawing and confirm the strike condition, since the 585 supplies a universal top strike and a mortise bottom strike.
14) What finish does the Rockwood 585 surface bolt come in?
UD26D, Rockwood's satin chrome over steel. It is the standard commercial match, so it sits alongside 626 satin chrome lever trim and closers on the same opening without looking off.
