Modular cylinders
Introduced in April 2010, the Schlage
modular cylinder provides easy
convertibility between key-in-lever to
mortise and rim cylinders. These
benefits make Schlage cylinder
inventory flexible, reduce the size and
cost of inventory and customer lead
time, and increase customer
satisfaction. With a few modular
components in stock, the cylinder type
and finish required will always be on
hand. The modular cylinder accepts a
tailpiece or a mortise cam.
Product line availability: A, AL, B, CL, D, H, L, ND, S, S200,
Kryptonite (PL, KS, KC), and Rim (standard and lockout).
All competitive locks that accept Everest® Primus will also
accept the modular cylinders.
