Rockwood 580-8 US26D – Frequently Asked Questions
1) Will a Rockwood 580 surface bolt throw far enough into my existing top strike and floor strike?
Bolt throw on the 580 is 1-1/8 inches, with a bolt bar measuring 1/4 by 3/4 inch. Both the 580 and 582 series ship with a universal top strike and a mortise bottom strike, so you are not depending on whatever is already in the frame and floor. If your existing floor condition will not take a mortise strike, plan on a surface strike or a different bolt.
2) What bolt lengths does the Rockwood 580 come in, and which one do I need?
Three lengths: 8 inch, 12 inch, and 24 inch. Length is the bolt body, not the throw, so it is about reach and where the operating handle lands. An 8 inch is the usual pick for a bottom bolt within easy reach; 12 and 24 inch are how you get the top bolt handle down to a workable height on a tall or standard-height leaf without a ladder. Throw stays 1-1/8 inches regardless of the length you order.
3) Does the Rockwood 580 surface bolt meet ANSI A156.16?
Yes, the 580 carries ANSI A156.16 with type number L04161, which is the auxiliary hardware standard covering surface bolts. That is the line a spec writer or institutional buyer needs on the submittal, and it pairs with the UL listing for 3-hour labeled fire door pairs.
4) What is a comparable heavy duty surface bolt to the Rockwood 580 for the inactive leaf of a 3-hour labeled fire door pair?
The Rockwood 580 is UL listed for use on the inactive leaf of a pair of 3-hour labeled fire doors, with a 1-1/8 inch bolt throw and 1/4 inch by 3/4 inch bolt material. The Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, carrying a 3-hour UL listed fire rating. Both are steel and both suit a labeled pair, so the decision comes down to throw depth and whether you want the SB1630 keyed locking feature, which the 580 does not have.
5) Which surface bolt has a deeper throw than the Rockwood 580?
The Rockwood 580 throws 1-1/8 inches with 1/4 inch by 3/4 inch bolt material. If the opening needs more engagement into the strike, the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw and is fire rated. The Ives SB360 sits between them at a 1-1/4 inch throw in heavy-duty steel, also fire rated, in a 12 inch length that matches one of the three 580 bolt lengths.
6) I need a surface bolt that also takes a padlock. Does the Rockwood 580 do that, or do I need something else?
The Rockwood 580 series does not carry a padlock provision; the companion Rockwood 582 series has a bracket for a padlock, with the padlock supplied separately. Both series include a universal top strike and a mortise bottom strike. If you want the security built into the bolt rather than added with a padlock, the Ives SB1630 is a heavy duty steel locking surface bolt with keyed security and a 1 inch throw.
7) What screws come with a Rockwood 580 surface bolt, and do I need anything else to mount it?
Each 580 ships with 8 each #10 x 1-1/4 inch flat head sheet metal screws and 8 each #10-24 x 1 inch flat head machine screws, which covers wood and metal door mounting. Sex bolts are available as an option for more secure through-bolted mounting, and they are worth specifying on a hollow metal or high-abuse opening where screws into the face can be pulled. No padlock or padlock bracket on the 580.
8) Difference between the Rockwood 580 and the 582 surface bolt?
Both series include a universal top strike and a mortise bottom strike and share the same 1-1/8 inch throw and 1/4 by 3/4 inch bolt. The 582 adds a bracket for a padlock, so the inactive leaf can be padlocked shut; the padlock is not supplied. If you do not need a padlock point, the 580 is the one to order. Note the UL listing for the inactive leaf of a 3-hour labeled pair is called out on the 580 series.
9) Is the Rockwood 580 surface bolt stainless steel?
Substrate is stainless steel, with steel and stainless steel both called out for the series, and it is finished US26D (satin chrome). Stainless is the reason it holds up on exterior-facing pairs, wash-down areas, and high-traffic institutional corridors where a plated steel bolt would rust at the rod. For a solid brass surface bolt instead, look at the Emtek 8511 or the Delaney solid brass surface bolt.
10) Should I use a surface bolt or a flush bolt on the inactive leaf of a pair of doors?
A surface bolt like the 580 mounts on the face of the inactive leaf, so it needs no mortising into the door edge and can be added to an existing pair without routing. That makes it the retrofit choice when a pair was never prepped for flush bolts. The trade-off is that it is visible on the door face and reachable by anyone on that side. Flush bolts hide in the door edge but require factory or field prep. The 580 gives you a 1-1/8 inch throw into an included top strike and mortise bottom strike, and it is UL listed for the inactive leaf of a 3-hour labeled pair.
11) Is the Rockwood 580 heavy enough for a commercial building, or is it a residential bolt?
The 580 is a commercial surface bolt, stainless steel, carrying ANSI A156.16 and a UL listing for the inactive leaf of a 3-hour labeled pair. Rockwood hardware of this type goes into institutional buildings, schools, detention, hotels, and offices. If you want a heavier bar or an auto-locking action, the ABH HD1805 uses a 3/4 inch stainless bar with auto-locking, and the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw. Decorative solid brass bolts like the Delaney BV7600 are a different class of product and belong on residential openings.
12) What are the other commercial surface bolt series to consider alongside the Rockwood 580?
The Rockwood 580 series meets ANSI A156.16, L04161 in stainless steel. On the commercial side, the Trimco 4800 series and the ABH HD1805 series are the other full surface bolt lines to look at; the ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, which is a heavier bar than the 1/4 inch by 3/4 inch bolt material on the 580 and self-locks when thrown. For standardizing a facility on one series, match the bolt length you need against the 8, 12 and 24 inch lengths the 580 covers.
13) Can I use a brass fire rated surface bolt in place of the Rockwood 580?
The Ives SB1640 is a fire rated surface bolt of brass construction with a 1 inch throw, so it is an option where a brass finish is wanted on a rated opening. The Rockwood 580 is steel and stainless steel with a 1-1/8 inch throw and is UL listed specifically for the inactive leaf of a pair of 3-hour labeled fire doors, and it ships with 8 each #10 x 1-1/4 inch FH SMS and 8 each #10-24 x 1 inch FH MS fasteners, with sex bolts available for more secure mounting.
14) Will the Rockwood 580 surface bolt match the US26D hardware already on my other doors?
Finish is US26D, satin chrome, which is the standard commercial finish on levers, closers, and push plates in most institutional and office buildings. If the rest of your openings are US26D, the 580 will read the same across the fleet. It is stainless steel underneath, so wear at the handle does not expose a contrasting base metal the way plated steel does.
