Beer Tap Handle Anatomy: Parts, Thread Size, Height, Install, and Tower Spacing
Updated September 2026 by Brad Lugar, owner of Steel City Tap Co., Birmingham, AL.
Quick answer: A beer tap handle is a body (resin, wood, metal, or acrylic) with a threaded metal ferrule set in the base. The ferrule is 3/8-16, which fits the lever on every standard US beer faucet. Most handles are 10 to 12 inches tall; compact shapes are around 7. To install, screw the handle onto the faucet lever until snug, then use the faucet's jam nut or collar to set which way it faces. On a tower, plan on roughly 3 inches between faucet centers and keep handle width under that.
We build tap handles in Birmingham, AL, and our ferrules are made to our own drawing, so this is the reference post for the questions we get about the hardware.
What a tap handle is made of
- Resin. Cast in a mold, so any shape is possible: cans, bottles, mascots, figures. Painted and clear coated. The material for fully custom shapes. Resin tap handles.
- Wood. Cut and finished from American sourced stock, printed full color under a UV clear coat. The craft look. Wood tap handles.
- Metal. A thin printed blank, often with a magnetic insert so the label can swap. Fits tight towers. Metal tap handles.
- Acrylic. Clear or colored, printed or engraved. Modern look, light weight.
The ferrule and the thread
The ferrule is the metal fitting in the base of the handle. Ours is brushed aluminum, tapered, and threaded 3/8-16 UNC on the faucet side, which is the standard thread on US beer faucet levers. If a handle does not fit your faucet, the thread is wrong, usually because it came from overseas. We sell the ferrule on its own for repairs and shop built handles.
How tall should a tap handle be?
10 to 12 inches for most bar towers. Tall enough to read over a row of pint glasses, short enough to clear the back bar shelf and the bartender's reach. Compact shapes around 7 inches (like our lollipop) fit crowded walls and low clearances. Anything over 13 inches needs a tower with room above it.
How to install a tap handle
- Thread the handle onto the faucet lever clockwise until it is snug. Hand tight is enough.
- If the handle stops facing the wrong way, back it off slightly and tighten the faucet's jam nut (the collar on the lever) up against the handle base to lock the facing. Do not overtighten; the ferrule is aluminum and the lever is brass.
- Pull to pour. The lever should travel fully open with no contact against the neighboring handle.
For wine, cider, coffee, or cocktail faucets: same thread, same install.
Tower spacing
Most commercial towers space faucets around 3 inches apart, center to center, though it varies by tower. A handle wider than the spacing hits its neighbor when the lever swings. Keep the handle body under about 2.5 inches wide at the widest point for a standard tower, or check the tower before you approve a wide sculpted design. We ask for tower spacing on every custom order for this reason.
Care
Wipe with soap and water. No solvents, no dishwasher. A UV clear coated handle on a bar will look the same for years; the only thing that ruins them is a bartender with a bottle of bar cleaner.

Frequently asked questions
What thread size is a beer tap handle?
3/8-16 UNC. That is the standard thread on US beer faucet levers, and every Steel City Tap handle ships with a 3/8-16 ferrule.
How do you install a tap handle?
Screw it clockwise onto the faucet lever until snug, then tighten the faucet's jam nut against the handle base to lock the facing. Hand tight only.
How tall is a standard tap handle?
10 to 12 inches for most bar towers. Compact handles are around 7 inches for crowded walls and low clearances.
How far apart are tap handles on a tower?
Most commercial towers put faucets about 3 inches apart center to center, so handle bodies should stay under about 2.5 inches wide. Check your tower before approving a wide design.
What is a tap handle ferrule?
The threaded metal fitting set in the base of the handle. Ours is brushed aluminum, tapered, threaded 3/8-16, and sold separately for repairs and shop built handles.
