📘 FAQs – Spindles

❓ What is a spindle used for in door hardware?

A spindle is a square metal rod that connects the handles or knobs on either side of the door, allowing them to operate the latch or lock mechanism when turned.

❓ What size spindle do I need?

Spindles come in various lengths (usually 100 –150mm) and thicknesses (common sizes are 7mm, 8mm, and 5mm). The correct size depends on your door thickness and handle type.

❓ What’s the difference between a standard and split spindle?

• Standard spindles rotate the latch from both sides.

• Split spindles allow independent operation on each side — ideal for multi-point locking or external doors with security handles.

❓ Can I cut a spindle to size?

Yes – many standard spindles are mild steel and can be trimmed to length using a hacksaw if needed. Always measure carefully first.

❓ Do I need a different spindle for knobs vs. levers?

Some doorknobs require longer or grooved spindles, especially if unsprung. Levers often use 7mm or 8mm standard spindles. Check your handle spec for compatibility.

❓ What is a grooved spindle?

Grooved spindles are designed for grub screw fixings on handles or knobs that need to grip the spindle directly, common with unsprung hardware.

❓ Are privacy spindles included in bathroom sets?

Most bathroom thumbturns come with a privacy spindle, but if you're building a custom set, you may need to buy one separately.
