Sargent 10-0503 26D – Frequently Asked Questions

1) Is the Sargent 10-0503 a replacement part or a complete lock?
It is trim only. The 10-0503 is a replacement L Design turn button trim component that mounts onto an existing Sargent 7-Line or 10-Line lock assembly. You still need the lock body, chassis and latch. Order it when the turn button trim is damaged, worn, or being refinished, not when you are replacing a whole lockset.
2) Can a Corbin Russwin 483F80 lever be used in place of the Sargent 10-0503 turn button trim?
No. The Sargent 10-0503 is L Design turn button lock trim with a T-Turn and the 30 option, built for Sargent 7-Line and 10-Line lock assemblies. The Corbin Russwin 483F80 is an outside lever and spindle for the ML2000 Series, listed for a 1-3/4 inch thick door in a Corridor/Dormitory function. One is the inside thumb-turn piece of a Sargent lock, the other is a lever trim for a different manufacturer's mortise line, so they are not interchangeable and neither will mount to the other's chassis.
3) What finishes does the Sargent 10-0503 L Design turn button trim come in?
Twelve finishes, so you can match existing openings in a building: 03 Bright Brass, 04 Satin Brass, 09 Bright Bronze, 10 Satin Bronze, 10B Dark Oxidized Satin Bronze Oil Rubbed, 10BL Dark Oxidized Satin Bronze Clear Coated, 15 Satin Nickel, 20D Dark Statuary Bronze Lacquered, 26 Bright Chrome, 26D Satin Chrome, BSP Black Suede Powder Coat and WSP White Suede Powder Coat. For a fleet of doors, 26D is the usual commercial standard and 10B the common decorative choice.
4) What does the T-Turn and 30 option mean on this Sargent lock trim?
The T-Turn is the thumb-turn style on the inside trim, giving a positive lock and unlock action by hand rather than by key. The 30 option is Sargent's configuration designation carried by this part. Both are already built into the 10-0503 as supplied, so there is nothing extra to specify on the order beyond finish.
5) Is this Sargent turn button trim rated for commercial traffic?
Yes, it is a commercial-duty part, built to Sargent's commercial lock trim standards and used in offices, schools, healthcare, retail and multi-tenant residential buildings. It is not a residential-grade thumbturn.
6) If I am standardizing finishes across a building, does the Sargent 10-0503 give me more finish choices than a Corbin Russwin ML2000 lever?
The Sargent 10-0503 turn button trim is offered in twelve finishes, including 03 Bright Brass Clear Coated, 04 Satin Brass, 09 Bright Bronze, 10 Satin Bronze, 10B Dark Oxidized Satin Bronze Oil Rubbed, 10BL, 15 Satin Nickel, 20D Dark Statuary Bronze Lacquered, 26 Bright Chromium, 26D Satin Chromium, BSP Black Suede Powder Coat and WSP White Suede Powder Coat. The Corbin Russwin 483F80 is specified by its ML2000 Series LW lever and 1-3/4 inch door thickness rather than by a finish range, so for a finish-driven standardization program the Sargent trim gives you the explicit finish menu to spec against.
