Schlage B520-722 – Frequently Asked Questions
1) What lengths does the Schlage B520-722 cylinder back housing come in?
Four lengths: 1-1/4, 1-1/2, 1-5/8 and 1-3/4 inches. The length you need is set by the cylinder length the door prep and mortise lock already use, so measure the housing you are pulling out rather than the door thickness. Order the matching size and the rest of the modular mortise cylinder assembly carries over.
2) What exactly is the B520-722 part, the whole cylinder or just a piece of it?
It is only the back housing, the body section of a Schlage modular mortise cylinder. You are not getting a keyed plug, cam or keys with it. Buy it when the housing itself is damaged or you need a different length and want to reuse the existing core and cam.
3) Will a Schlage B520-722 housing fit any mortise cylinder, or only Schlage?
Only Schlage modular mortise cylinders. It is a genuine OEM part machined for that assembly, so it will not accept another manufacturer's plug or mate with another brand's cylinder body. If the door has a non-Schlage mortise cylinder, replace the cylinder rather than the housing.
4) Can I standardize mortise cylinder housings across a building with this part?
Yes, if the openings already run Schlage modular mortise cylinders. Keeping the B520-722 on the shelf in the lengths your doors use lets maintenance swap a damaged housing and reuse the keyed core, so keying stays as it is across the facility. Four lengths cover the range: 1-1/4, 1-1/2, 1-5/8 and 1-3/4 inches.
5) We are standardizing a building on interchangeable core keying - do I order the Schlage B520-722 or an Ilco convertible housing?
Order by the core platform you are standardizing on. The B520-722 supports Schlage modular mortise cylinders, offered in 1-1/4 inch, 1-1/2 inch, 1-5/8 inch and 1-3/4 inch lengths for different door and lock depths. For small format IC keying, the Kaba Ilco R2800 Series is a small format IC core convertible housing; for large format IC in the Schlage size, the Kaba Ilco S26506 is a mortise convertible housing.
6) Is the B520-722 housing rated for commercial door traffic or is it a residential part?
Commercial. Schlage builds the B520-722 to its commercial door hardware standards, and it is used in offices, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings.
