🔑 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
