What Mounting Tabs Are and Why They Exist
This is the content gap on every competitor page. None explain what the tabs actually do or why there are three different mounting methods in the first place.
An Adams Rite MS deadlock or deadlatch mounts inside the hollow tube of a narrow stile aluminum door. To hold it there, the lock case needs mechanical attachment points screw anchors inside the stile that the lock case threads into from the door face. On a new door built for Adams Rite hardware, these attachment points are already there. On an existing door where the original lock used a different mounting pattern, or where the door has no pre-drilled lock prep at all, you need to create attachment points without drilling through the glass-bearing stile face.
The 91-0966 is the Method C solution to this problem. The tabs mount from the edge of the door rather than through the face they clip or screw into the beveled door edge, creating the screw anchors the lock case needs on both sides, without touching the stile face and without risking the glass-adjacent stile wall. The Adams Rite catalog calls this out explicitly: edge-location mounting reduces risk of door damage, particularly on glass doors, and makes drilling an easier process compared to Methods A and B.
"Stylelock to Sentry Lock Retrofit Kit": What This Search Means
If you searched "stylelock to sentry lock retrofit kit" Stylelock and Sentry Lock are brand names of narrow stile aluminum door hardware used on commercial glass storefront doors. Both use similar door stile mounting patterns to Adams Rite, and when a door with a Stylelock or Sentry Lock fails and needs replacement hardware, Adams Rite MS locks are the standard retrofit choice.
The 91-0966 mounting tab kit is what enables that retrofit when the existing door prep does not match the Adams Rite mounting pattern exactly. Instead of drilling new holes through the stile face or modifying the door, the tabs attach at the edge of the door in the beveled stile channel and create the mounting points for the Adams Rite lock case. This is the reason the 91-0966 is categorized as a retrofit kit on the Adams Rite catalog page for lock mounting methods it was specifically developed for retrofitting locks into existing aluminum door jams.
The Three Adams Rite Mounting Methods: Where the 91-0966 Fits
Adams Rite's catalog documents three methods for mounting locks in narrow stile aluminum doors:
Method A 4104 Mounting Bridge: A steel bridge spans the stile top and bottom of the lock case and is tightened using the Adams Rite 4075 installation tool to form a structural web inside the door stile. The standard new-construction method for Adams Rite installations.
Method B 26-0009XX Tube Spacer: Requires two tapped holes in the back web of the stile and tubular spacers of appropriate length. Used when the back web of the stile can be drilled and tapped. Some door manufacturers use a coil spring instead of a tube spacer.
Method C 91-0965 (flat/radius stile) and 91-0966 (beveled stile): The retrofit method, developed specifically for installing locks into existing aluminum door jams. Attaches from the edge of the door rather than through the stile face. Works in aluminum, metal, and steel doors. The 91-0966 is this kit for beveled stiles.
91-0966 vs 91-0965: Beveled vs Flat and Radius Stiles
The only difference between these two kits is the stile edge profile they are designed for:
91-0965 (flat/radius stiles): For doors where the edge of the door is square (flat) or has rounded ends (radius profile). This is the more common stile profile on standard aluminum storefront doors.
91-0966 (beveled stiles this listing): For doors where the edge of the door is cut at a slight angle a bevel toward either the left or the right. The 91-0966 covers both bevel directions in one kit: tabs for right-hand bevel and tabs for left-hand bevel doors are both included in the same package.
Confirm your door stile edge profile before ordering. A flat/radius stile will not seat the 91-0966 beveled tab correctly, and a beveled stile will not accept the 91-0965 flat tab flush.
What the Kit Includes
The 91-0966 includes tabs for right-hand bevel doors, tabs for left-hand bevel doors, and mounting screws for two finish environments: clear anodized aluminum and dark bronze anodized. This means one kit covers both bevel directions and both standard commercial aluminum finish families without separate screw orders. Select the screws matching your door's anodized finish to maintain a consistent appearance at the door edge.
Compatible Locks
The 91-0966 is compatible with the full Adams Rite MS Series deadlock and latch family MS1850S, MS1850SN, MS1950 Series deadlocks, and Adams Rite deadlatch Series including 4500, 4900. Any Adams Rite MS lock or latch that uses the standard Method C mounting pattern is compatible with this tab kit.
The kit also works in metal and steel doors in addition to aluminum confirmed in the Adams Rite catalog specification for Method C mounting.
