Schlage H Series A508-600 - Housing, A43/79

The A508-600 is the housing on its own, a Schlage H Series service part called out for the A43 and A79 functions. It is sold as a repair part, so ordering it gets you the housing rather than a complete lockset. It is a commercial part, not residential.

Only the functions it is built for. The A508-600 housing is specified for A43 and A79 in the Schlage H Series, and a lock built to a different A-Series function takes the housing that matches that function instead. Read the function code off the lock you are repairing before you order this one.

It does. Many Schlage service parts are made finish specific, and on Schlage part numbering the finish rides in the suffix, so order the housing as A508-600 rather than by the base number alone. That is what keeps a repaired lock matching the trim already on the rest of the doors.

Depends on the lock body you are servicing. A housing part like the Schlage A508-600 is a repair piece for H Series A43/79 locks, so it is the wrong item if what you want is a keyed cylinder. For a rim exit device, the Sargent Signature 10-34 is a 6-pin rim cylinder. For a mortise lock, the Sargent Signature 10-40 6-pin mortise cylinder. For a deadbolt, the Sargent Signature 10-ALC 6-pin deadbolt cylinder assembly. All three carry protected key control.

If turnover drives frequent rekeying, removable core saves the labor. The Sargent 10-6300 Signature LFIC removable core cylinder ships with a factory-installed cam, and a large format interchangeable core pulls with a control key instead of taking the lock apart to repin it. Fixed cylinders such as the Sargent Signature 10-40 mortise cylinder are a separate keying platform, so pick one and standardize the facility on it rather than mixing the two.

No, those are two different kinds of part. The A508-600 is the Schlage H Series housing for the A43/79 and is supplied as a replacement part for commercial door hardware. The Sargent Signature 10-40 is a 6-pin mortise cylinder with protected key control in Sargent's 40 Series - a complete threaded cylinder that turns a mortise lock body, not a housing that carries a Schlage A-series cylinder. If the A43/79 housing is what is damaged or wrong-finish on the door, the 10-40 will not fill that role; it belongs in an opening prepped for a mortise cylinder.

A rim device takes a rim cylinder, which is a different part from the A508-600 H Series housing for the A43/79. The Sargent Signature 10-34 is a 6-pin rim cylinder with protected key control in Sargent's 34 Series, and it is the shape of part a rim exit device is prepped for. Order the A508-600 only when the A43/79 housing itself is what is being replaced.

Those are not interchangeable. The A508-600 is the Schlage H Series housing for the A43/79, a replacement part for that Schlage hardware. The Sargent 10-6300 is a Signature LFIC removable core cylinder in the 6300 Series that comes with a factory-installed cam, built to drive a lock through that cam and to accept a large format interchangeable core. A cam-driven removable core cylinder and an A43/79 housing address different points in the opening, so substituting one for the other changes what has to be prepped and what keys the door.

The A508-600 is the H Series housing for the A43/79 and is matched to that hardware, not to a deadbolt. A deadbolt is served by its own cylinder assembly - the Sargent 10-ALC is a Signature Series 6-pin deadbolt cylinder assembly with protected key control, sold for that application. Specify by what is in the door: A43/79 hardware takes the A508-600 housing, a deadbolt takes a deadbolt cylinder assembly.

On the Sargent side, the parts described with protected key control are the 10-34 6-pin rim cylinder in the 34 Series, the 10-40 6-pin mortise cylinder in the 40 Series, and the 10-ALC Signature Series 6-pin deadbolt cylinder assembly. Those are the pieces that carry the key control program across rim, mortise, and deadbolt applications. The Schlage A508-600 sits outside that decision - it is the H Series housing for the A43/79, a commercial replacement part that restores the Schlage opening it belongs to rather than a piece that sets the keying platform for a building.
