Simplex 4100-9922 — three-bay beige glass-door retrofit kit for putting 4100ES equipment in an existing six-unit 2120 or 4100 Series deep back box.
Simplex made the 4100ES cabinet narrower, taller and deeper than the 2120, 2001 and 4100 Series boxes, so ES equipment will not drop into an old enclosure. These kits close that gap and let the installed box stay in the wall. Each supplies a door, retainer panels for glass-door applications, and box extension hardware.

Three neighbours differ by one attribute each: 4100-9920 is red glass-door three-bay, 4100-9926 is beige with a solid door, and 4100-9921 is two-bay beige glass-door. Shallow 6 1/2 in. boxes take different kits.
