Sargent SGT-1SB – Frequently Asked Questions

1) What is the Sargent 1SB and what does it actually do on a mortise lock?
The 1SB is a cylinder collar, a ring that sits between the mortise cylinder and the door face. It supports the cylinder and holds it in correct position within the mortise lock assembly. It is not a cylinder, not a rose for the lever, and not the lock itself. Sargent lists it as the standard collar for the 7800 BHD, 8200 BHL, and BHW mortise lock series. If you need the cylinder itself or the trim, the 1SB will not substitute for either.
2) Which size Sargent 1SB cylinder collar do I need for my door?
The 1SB comes in four collar thicknesses: 5/16 inch, 7/16 inch, 9/16 inch, and 11/16 inch. The size you pick is what makes up the gap between the mortise lock case and the face of the door, so it depends on your door thickness and how far the cylinder needs to stand off. Measure how much the cylinder currently projects past the lock body before ordering, and match a collar to that. All four are the same 1-29/32 inch diameter.
3) What diameter is the Sargent 1SB mortise cylinder collar?
1-29/32 inches across. That diameter is what decides whether it covers the cylinder prep cleanly on the door face, so if you are replacing an existing collar, measure the old ring before you order. A collar smaller than the hole in the trim leaves a gap; one larger will foul the escutcheon or rose.
4) What finishes does the Sargent 1SB cylinder collar come in, and can I match my existing door hardware?
Fourteen finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BE dark oxidized satin bronze, 10BL dark oxidized satin bronze clear coated, 14 bright nickel, 15 satin nickel, 20D dark statuary bronze lacquered, 32 bright stainless, 32D satin stainless, BSP black suede powder coat, and WSP white suede powder coat. Match the collar to the finish code stamped on your existing Sargent trim, not by eye. 32D satin stainless is the most common on commercial openings.
5) I am replacing a damaged cylinder collar on a Sargent mortise lock. Is the 1SB a repair part I can order on its own?
It is. Sargent catalogues the 1SB as a replacement part, so you can order the collar by itself without buying a new lock or trim set. For a property manager with a scuffed or missing collar on an otherwise sound 8200, that is the whole fix: match the finish code and the collar thickness on the good doors and swap it.
6) Do I need a specific cylinder collar thickness when I install an 8200 with BHL trim?
Yes, the collar thickness is part of the install, not an afterthought. Sargent publishes install instructions for the 8200 with BHL trim and a template covering 8200 and 9200 BHD, BHL and ALP trim, and both call out where the collar sits in the stack. Work from those before choosing between the 5/16, 7/16, 9/16 and 11/16 inch collars, since the wrong thickness leaves the cylinder either proud of the trim or too deep to turn the cam freely.
7) I am standardizing mortise hardware across a facility. Can I use one Sargent 1SB collar spec on every door?
You can standardize on the finish and the series, but not necessarily on one size. The 1SB is offered in 5/16, 7/16, 9/16 and 11/16 inch thicknesses because door thicknesses and cylinder projections vary from opening to opening. Survey a sample of doors, group them by the collar thickness they take, and order to those groups in a single finish code so the building reads consistently.
8) Is the Sargent 1SB collar suitable for a commercial building, or is it a residential part?
Commercial. Sargent lists the 1SB as a commercial product, and it belongs to the conventional key system line, meaning it is meant for standard mortise cylinders rather than an interchangeable core setup. Stainless steel construction holds up in high-traffic openings such as schools, hospitals, offices and multi-tenant buildings.
9) Is the Sargent 1SB stainless steel or plated brass?
The 1SB collar is stainless steel, which is why it resists corrosion in wet or heavily cleaned environments like healthcare and food service. The brass, bronze and nickel finish codes are surface finishes over that body, and the BSP and WSP options are powder coat.
