🔑 Commercial Lever & Ball Knob Tailpieces – Length Comparison
Shown in the photo: three different commercial tailpiece lengths, commonly used with lever handles and ball knobs.
📏 Left to right
-
Short tailpiece – For thin doors (metal, aluminum, narrow stile doors)
-
Standard tailpiece – Most common size for commercial wood & steel doors
-
Long tailpiece – Thick doors, storefronts, retrofits, or special installations
⚠️ Why length matters
Using the wrong tailpiece length can cause:
-
Hard or stiff turning
-
Lever not returning properly
-
Lock binding
-
Premature failure of the handle or lock body
🛠️ Professional locksmith tip
Tailpieces must be:
-
Correct length

Proper style (flat / square / IC-compatible)
-
Aligned and tested after installation
