Arrow B17-56 26D – Frequently Asked Questions

1) What exactly is the Arrow B17-56, a complete lock or just the lever?
The B17-56 is the outside lever only, a trim piece for Arrow BM-series mortise locksets. It is not a lockset, not a mortise case, and it does not include a cylinder or an inside lever. Buy it when the outside lever on an existing Arrow BM mortise lock is worn, bent, or damaged and the case itself is still good.
2) Can a Corbin Russwin 483F80 outside lever be used to replace an Arrow B17-56 lever on a BM mortise lock?
No. The Arrow B17-56 is an outside lever made as a genuine replacement part for Arrow BM-series mortise lock sets, so its spindle and hub engagement match that chassis. The Corbin Russwin 483F80 is an LW outside lever and spindle for the ML2000 Series, sized for a 1-3/4 inch thick door. Each lever is keyed to its own manufacturer's mortise chassis, so a BM-series lock body takes the Arrow lever and an ML2000 body takes the Corbin Russwin part.
3) I need a Grade 1 corridor/dormitory mortise lever - is the Arrow B17-56 the right part?
The B17-56 is a replacement outside lever for existing Arrow BM-series mortise lock sets and is specified by finish rather than by lock function, so the function comes from the BM lock body already in the door. If the requirement on the drawing is a Grade 1 corridor/dormitory mortise lever assembly, the Corbin Russwin 483F80 is listed as Grade 1 with a Corridor/Dormitory function in the ML2000 Series.
4) What finishes does the Arrow B17-56 mortise lever come in?
Eight finishes, by BHMA number: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, and 630 satin stainless steel. If you are matching other openings in a building, order by the BHMA number stamped on or specified for the existing hardware rather than by the finish name, since 626 satin chrome and 630 satin stainless look similar but are not the same.
5) Do I need to order the inside lever separately to rebuild an Arrow BM mortise lock?
Yes. The B17-56 covers the outside only. If the inside lever is also worn, that is a separate part. Same for the cylinder, rose or escutcheon, and spindle hardware that is not supplied with this lever.
6) Will replacing just the lever fix a mortise lock that feels loose or sloppy?
Often, yes, if the play is in the lever itself or its attachment to the spindle. A worn outside lever is exactly what this part is sold to replace, and it restores the lock to original spec without pulling the case out of the door. If the looseness traces back to the hub inside the mortise case, the lever alone will not cure it and the case needs service or replacement.
7) Does the Arrow B17-56 outside lever come with a spindle like the Corbin Russwin 483F80?
The Corbin Russwin 483F80 is supplied as an outside lever and spindle assembly for the ML2000 Series. The Arrow B17-56 is the BM mortise outside lever itself, supplied as a factory replacement trim part. If a job needs spindle hardware as part of the same item, that is how the 483F80 is packaged; for an Arrow BM lock, order the B17-56 lever for the trim replacement.
8) Which mortise outside lever gives me more finish choices for matching existing door hardware?
The Arrow B17-56 outside lever is offered in eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil-rubbed, 625 bright chrome, 626 satin chrome, 629 bright stainless steel, and 630 satin stainless steel. The Corbin Russwin 483F80 is specified as an ML2000 Series Grade 1 corridor/dormitory outside lever and spindle for a 1-3/4 inch door. For matching a mixed set of Arrow BM trim across a building, the B17-56 finish range covers brass, bronze, chrome, and stainless.
9) Is this Arrow lever rated for commercial traffic or is it residential grade?
Arrow classifies the B17-56 as commercial, built for mortise trim service in offices, schools, healthcare, retail, government buildings, multi-tenant residential, and industrial facilities. That is the traffic level the part is intended for.
