Schlage A Series A501-167 -Threaded Rod, to Mount A170 as Double Dummy

You need A170 dummy trim on each face joined through the door by the A501-167 threaded rod. The rod is the through-door connector that turns single-face A170 dummy trim into a double dummy, giving you a fixed pull on both sides with no latching function. That is the usual setup on the inactive leaf of a pair, on closet and french doors, and anywhere an opening needs hardware that matches the working locksets around it without actually latching.

Just the rod. The A501-167 is a Schlage service part, the threaded rod on its own, so the A170 trim is a separate line on the order. Building a double dummy from scratch means two A170 trims plus this rod. If you already have the trim off a door and the connector is missing or stripped, this is the only piece you are short.

No. This is a Schlage A Series part specified to mount the A170 as a double dummy, sold as a Schlage replacement component rather than a universal through-bolt kit. If the trim already on the door is not Schlage A Series, order the double dummy mounting hardware from that manufacturer's own line instead of trying to adapt this rod to it.

Order it against the finish of the A170 trim it is going into. Schlage builds many A Series service parts to a specific finish rather than one universal version, so treat finish as part of the part number rather than assuming a single rod covers every trim finish on the building.

Commercial. It belongs to Schlage's A Series line, so it is the correct service part for office, multi-family and institutional doors already running A Series trim. For a property manager standardising a building, that matters: keeping the double dummy openings on the same A Series family as the working locksets means one parts list and one finish across the floor.
