Trimco 243/244 Series Cane Bolts

That's exactly what they're for. The 243/244 cane bolts are top and bottom surface bolts for pairs of doors, so the inactive leaf gets bolted into the head above and the floor or threshold below, and the active leaf latches against it. The 243T is the 15 inch top bolt and the 244B is the 30 inch bottom bolt. Order both if you want the inactive leaf secured at head and sill; a single bolt only holds one end.

Two stock lengths: the 243T top bolt is 15 inches and the 244B bottom bolt is 30 inches. The 30 inch bottom bolt is the one that reaches down to floor strike height from a normal push-bar or mid-door mounting position, and the 15 inch top bolt throws up into the frame head. Trimco will also make a cane bolt to any length required if neither stock size reaches your strike.

Yes. Trimco makes the 243/244 cane bolts to any length required as a custom order, so an oversize or tall pair of doors is not a problem. Measure from your intended mounting height down to the floor strike (or up to the head) and specify that overall length when you order.

Solid. The 243/244 cane bolts are cast from solid brass or bronze, made in the United States, with architectural finishes applied over that base metal. That matters on exterior pairs and in corrosive or coastal environments where a plated steel bolt rusts at the rod and seizes in the strike.

Five finishes, and both the 15 inch top bolt and the 30 inch bottom bolt come in all five: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 625 bright chrome, and 626 satin chrome. If you are matching existing hardware on the opening, 626 satin chrome and 613 oil rubbed bronze are the two that pair with the most common commercial lever and hinge finishes, and ordering both bolts in the same code keeps the leaf consistent top to bottom.

Different jobs. A cane bolt like the Trimco 243/244 is a surface mounted, cast decorative bolt, so it goes on the face of the door with no mortising and stays visible and reachable, which is why it suits heavy commercial, industrial, and gate style pairs where someone needs to operate it by hand. A flush bolt is mortised into the edge of the leaf and hides completely, which is what you want on a finished interior pair where appearance rules and on most fire rated pairs. If you are cutting into a factory prepped or fire rated door, check what that door is prepped for before choosing surface mount.

Commercial. The 243/244 cane bolts are commercial grade cast brass or bronze, and Trimco lists them for commercial and industrial buildings, government and military facilities, hospitality, multifamily and mixed use, and office buildings. For a property manager standardizing a building, the same two models in one finish cover every pair of doors in the portfolio.

Yes, they are ordered as separate items. The 243T is the 15 inch top bolt and the 244B is the 30 inch bottom bolt, each with its own finish choice, so a fully bolted inactive leaf takes one of each. Buying a pair of doors' worth means two 243T and two 244B only if you are bolting both leaves, which is unusual; most openings bolt the inactive leaf alone.
