Emtek 8515 Solid Brass Surface Bolt, 8"

Holding the inactive leaf of a pair is exactly what the 8515 does. It's an 8 inch solid brass surface bolt that mounts on the face of the door and shoots a rod into a strike, so the inactive leaf stays put and the active leaf latches against it. Emtek classes it as residential hardware, so it suits interior French doors, patio pairs, and closet pairs rather than a commercial opening under a fire label. It ships as a complete set with three types of strikeplates and the screws, which covers the usual mounting conditions at the head, the sill, or the jamb.

Emtek builds this solid brass surface bolt in five lengths, each with its own model number: 6 inch is the 8511, 8 inch is the 8515, 12 inch is the 8512, 18 inch is the 8513, and 24 inch is the 8514. Length is about reach and proportion, not strength, so pick by where you want the thumb throw to sit. A bolt mounted low on the door needs to be long enough that you aren't bending to the floor to work it, and a tall door usually looks right with a longer bolt. The 8 inch 8515 is the common choice for a standard interior pair.

No. The 8515 is residential hardware, and a fire rated opening needs a bolt that carries the label. Ives makes fire rated surface bolts in steel and in brass: the SB1600 is a heavy duty steel bolt with a 3-1/2 inch throw, the SB360 is a heavy duty steel bolt with a 1-1/4 inch throw in a 12 inch length, and the SB1640 is a fire rated brass bolt with a 1 inch throw if you want the brass look. The Ives SB1630 is heavy duty steel with a 1 inch throw and carries a 3-hour UL listing, plus it locks with a key.

The Emtek 8515 is a manually thrown solid brass surface bolt - you slide the rod by hand and it holds the leaf. If the inactive leaf has to be secured against someone on the other side, the Ives SB1630 is a heavy duty steel locking surface bolt with keyed security and a 1 inch throw. The ABH HD1805 is a heavy duty surface bolt with an auto-locking 3/4 inch stainless steel bar, which latches itself rather than needing a key. Choose the 8515 when the bolt is a hold-shut on a French door or closet, not a security point.

The Delaney Solid Brass Surface Bolt (DLY-410309) is the nearest like-for-like: same solid brass construction and the same decorative surface-bolt format as the Emtek 8515, which is a solid brass surface bolt in an 8 inch length. Delaney also builds a Decorative Solid Brass Surface Bolt (BV7600) if the door calls for a more ornamented plate. All three are surface-mounted bolts that screw to the face of the door and drop a rod into a strike, so the prep is the same regardless of which one goes on.

Twelve finishes on the 8515: Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), Satin Brass (US4), French Antique (US7), Oil Rubbed Bronze (US10B), Polished Nickel (US14), Satin Nickel (US15), Pewter (US15A), Flat Black (US19), Polished Chrome (US26), Medium Bronze (MB), and Tumbled White Bronze (TWB). Those are Emtek's standard finish codes, so ordering the 8515 in the same code as your knobs, levers, or hinges keeps the pair of doors consistent. Worth knowing: Unlacquered Brass has no clear coat and will patina with handling, so it won't stay matched to a lacquered US3 piece over time.

The 8515 is a thumb operated bolt, not a locking one. You throw and retract it by hand from the side it's mounted on, which makes it a privacy and stabilizing device rather than a security lock. If you need the bolt itself to lock, the Ives SB1630 is a heavy duty steel surface bolt with keyed security and a 1 inch throw. On a pair of doors most people run the plain bolt on the inactive leaf and put the actual lock on the active leaf.

Among brass bolts, the 8515 is the traditional American Classic profile, sold as a set in five lengths from 6 to 24 inches with three strikes in the box. Delaney makes two brass alternatives: a plain Solid Brass Surface Bolt and a Decorative Solid Brass Surface Bolt if you want a more ornamented face plate. On the steel side, the Trimco 4800 Series is another surface bolt family. The real dividing line isn't material, it's whether the opening is rated. Emtek's is residential; the Ives brass SB1640 is the fire rated brass option.

Yes, and that's the usual install on a pair. One bolt at the head shooting up into a strike in the frame, a second at the sill shooting down into a floor strike, and the inactive leaf is fixed at both ends. Order two 8515s for that, since each is sold as its own complete set with strikes and screws. Choose length per position: the 8 inch works well at the head, and some installers go longer at the bottom, up to the 24 inch 8514, so the throw sits at a comfortable height instead of at the floor.

The 8515 is designed for wood doors. It mounts with screws through the face plate and the strikes are screw applied too, so it wants solid material to bite into. Hollow metal is a different install, and the residential brass line isn't built for it. For a hollow metal opening, look at the steel heavy duty bolts: the Ives SB1600, SB360, or the ABH HD1805.

Emtek builds the same brass surface bolt family in a 12 inch size under model 8512, alongside 6 inch (8511), 18 inch (8513), and 24 inch (8514). If the opening needs more than a residential brass bolt at that length, the Ives SB360 is a heavy-duty steel surface bolt with a 1-1/4 inch throw in a 12 inch length. Same surface-applied install either way; the difference is steel heavy duty construction versus solid brass.

Not dimensionally. The Emtek 8515 is an 8 inch solid brass bolt, while the Ives SB360 heavy-duty steel bolt is a 12 inch length and the Ives SB1600 throws 3-1/2 inches versus the 1 inch throw on the Ives SB1640. Plate length and throw both change the screw pattern and the strike location, so a steel replacement generally means new holes in the door and a new strike position rather than dropping onto the existing prep. The Emtek 8515 ships as a complete set with three types of strikeplates and screws, which covers the common strike conditions when you are installing it fresh.

Ives is the line that spans it. The SB1600 is heavy duty steel with a 3-1/2 inch throw and is fire rated, the SB1630 is a heavy duty steel locking bolt with a 3-hour UL listed rating and keyed security, and the SB1640 is a fire rated brass bolt with a 1 inch throw - so a rated corridor door and an unrated back-of-house door can carry the same family. The Emtek 8515 is a residential solid brass bolt and fits the decorative side of a portfolio: apartment interiors, French doors, and unit closets rather than the rated openings.

The only thing that changes across the family is plate length: 8511 is 6 inch, 8515 is 8 inch, 8512 is 12 inch, 8513 is 18 inch, and 8514 is 24 inch, all solid brass. Model 8515 carries an 8 inch size, and finish is appended to the model - 8515MB for Medium Bronze, 8515TWB for Tumbled White Bronze, with Oil Rubbed Bronze ordered as SPC851510B. Against other brands the identity marker is construction: the 8515 is solid brass, where the Ives SB1600 and SB360 are steel and the ABH HD1805 uses a stainless steel bar.
