Repair damaged or missing lock-mounting points in aluminum storefront doors with the DON-JO TB-215 Mortise Lock Mounting Tab.

Designed as a compact steel mounting tab for commercial door hardware installations, the TB-215 provides a solid attachment point when installing or replacing compatible mortise deadbolts, hookbolts, and deadlatches in narrow-stile aluminum storefront doors.

Storefront Door Repair Application

The TB-215 is especially useful when the original mounting tabs inside an aluminum storefront door have become:

• Broken

• Bent

• Stripped

• Missing

• Damaged during previous hardware replacement

Instead of replacing the complete door stile, a compatible replacement mounting tab can provide a new attachment point for the mortise lock hardware.

Compatible Lock Applications

The TB-215 is commonly used with Adams Rite-style storefront mortise hardware, including compatible:

• Mortise deadbolts

• Hookbolt deadlocks

• Deadlatches

• Narrow-stile lock bodies

Always verify the lock body, mounting-hole spacing, door preparation, and available interior clearance before installation.

13-Gauge Steel Construction

DON-JO currently specifies the TB-215 as:

Material: Steel
Gauge: 13 Gauge
Thickness: .095"

The heavy steel construction provides a solid mounting surface for commercial lock hardware.

Dimensions

Length: 1-1/2"
Width: 1"
Offset: 1/8"
Thickness: .095"

The offset allows the tab to sit correctly within compatible storefront-door preparations while positioning the mounting surface for the lock body.

Raw Steel Finish

DON-JO catalogs the TB-215 with a:

Raw Steel Finish

Because it is an internal installation component, the tab is normally concealed within the door stile after the lock is installed.

Common Applications

Ideal for:

• Aluminum storefront doors

• Narrow-stile entrance doors

• Commercial glass doors

• Retail storefronts

• Office entrances

• Shopping centers

• Restaurants

• Schools

• Commercial buildings
