Trimco 4800 Series Surface Bolts

The 4800 Series slide bolt is offered in 2, 3, 4, 6, 12, 24, 36 and 48 inch lengths. Trimco calls 3, 4, 6 and 12 inch the standard sizes, and custom lengths are made for openings the stock sizes do not cover. Short bolts (2 to 6 inch) are the usual pick for the top or bottom of an inactive leaf where the strike sits close to the head or floor; the 24, 36 and 48 inch bolts reach from a comfortable hand height up to a transom or head strike on a tall opening, so nobody needs a ladder to throw it.

Both strikes ship with the bolt. Trimco supplies the 4800 Series with a universal strike and a mortise strike, so you can surface-apply the strike to the frame, floor or head, or mortise it in for a flush result, without a second line on the order. That covers the common cases: a bottom bolt dropping into a floor strike, or a top bolt into the head of the frame.

For a labeled fire door pair, specify a bolt that carries the rating on its own listing. The Ives SB1600 and SB1640 are fire rated surface bolts, and the Ives SB1630 locking bolt is listed 3-hour UL. Those are the ones to price for a rated opening. The Trimco 4800 Series is the solid bronze or brass standard duty choice for non-rated pairs where finish match to the rest of the trim is what matters.

The Trimco 4800 Series is a standard duty slide bolt in solid bronze or brass. For openings that need a heavier bolt, the ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, and the Ives SB1600 is a heavy duty steel surface bolt with a 3-1/2 inch throw. The Ives SB360 is a heavy duty steel surface bolt with a 1-1/4 inch throw in a 12 inch length. Those three are steel or stainless bars rather than the bronze and brass the 4800 uses, so the finish match to surrounding trim is a separate decision.

The Trimco 4800 Series is a slide bolt, thrown and retracted by hand. When the bolt itself has to resist being retracted, the Ives SB1630 is a heavy duty steel locking surface bolt with a 1 inch throw and keyed security, carrying a 3-hour UL listing, and the ABH HD1805 uses an auto-locking 3/4 inch stainless steel bar. Both change what the door needs at the head or sill compared with a hand-operated bronze slide bolt.

Five architectural finishes are made across every length: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 625 bright chrome and 626 satin chrome. Those are standard BHMA finish numbers, so matching is a matter of reading the number off the levers or hinges you already have and ordering the bolt in the same one. Trimco lists the finish range specifically so the bolts match the rest of the hardware on the opening.

No handing to specify. The 4800 Series is a surface applied slide bolt, so it mounts to the face of the inactive leaf and is oriented by where you put it rather than by a left or right hand designation. The order decisions are length and finish only.

A surface bolt like the Trimco 4800 mounts on the face of the leaf and needs no routing of the door, which makes it the retrofit answer when the leaf is already hung and has no bolt prep. A flush bolt is mortised into the edge of the door and sits out of sight, which is what you want on new work or where the face of the door has to stay clean. Solid bronze or brass, in five architectural finishes, means a surface bolt shows as trim rather than as an afterthought.

The 4800 Series is a plain slide bolt, thrown and released by hand with no key. That is what most inactive leaves need, since access is controlled by the lock on the active leaf. Where the bolt itself has to resist someone reaching it, the Ives SB1630 is a keyed locking surface bolt, and the ABH HD1805 auto-locks when thrown.

Two per inactive leaf is the normal count, one at the head and one at the bottom, so the leaf is held top and bottom and the active leaf latches into it. Each bolt arrives with its universal and mortise strikes, so a pair takes two bolts and no separate strike order. Lengths can differ between the two: a longer bolt up top puts the handle within reach, while a short 3 or 4 inch bolt is usually plenty at the floor.

The Delaney Decorative Solid Brass Surface Bolt is built as a decorative brass bolt, and the Emtek 8511 solid brass surface bolt in 6 inch is another brass option at a single length. The Trimco 4800 Series is a commercial bolt in solid bronze or brass, offered in architectural finishes including 605 bright brass, 606 satin brass and 613 oil rubbed bronze that are meant to match the rest of the hardware on the opening.

The Ives SB1640 is a fire rated brass surface bolt with a 1 inch throw. The Trimco 4800 Series is a standard duty solid bronze or brass slide bolt in 605 bright brass and 606 satin brass among its finishes, supplied with universal and mortise strikes, in lengths from 2 inches to 48 inches. Both are brass bolts; the SB1640 is the one to specify when the door schedule requires a fire rating, and the Trimco is the one that spans the wider length and finish range.

The Trimco 4800 Series covers 2, 3, 4, 6, 12, 24, 36 and 48 inch lengths in five finishes from one bronze or brass series, and it is ADA compliant, which keeps one part family across a mixed set of openings. Where a door needs a rating, the Ives SB1630 is a heavy duty steel locking bolt with a 3-hour UL listing and the Ives SB1600 is a heavy duty fire rated steel bolt with a 3-1/2 inch throw. Facilities commonly run the Trimco on non-rated openings and the rated Ives bolts where the door schedule calls for them.

Solid bronze or brass throughout, not plated steel. That is the material argument for this bolt over a steel one: bronze and brass do not rust, so a 4800 on an exterior pair or in a humid coastal or pool environment keeps working and keeps its appearance. The steel heavy duty alternatives, like the Ives SB1600 and SB360, trade that for more strength.
