Narrow stile doors require a trim ring to fill the gap remaining between the cylinder
shoulder and stile when a standard mortise cylinder is used. If the security of the
hardened steel Adams Rite MS4043 Cylinder Guard is not required, this ring may be
simply a length of 1.171 I.D. tubing. Its length varies depending on door thickness or
cylinder make and number of pins. The specific length required can be quickly
determined by the following formula:
