What is the best bolt type for double doors?

For double doors, flush bolts are commonly used to secure the inactive leaf. For taller doors or where stronger top-to-bottom security is needed, an espagnolette bolt can provide improved locking along the door height.

Are polished chrome door bolts suitable for bathrooms and kitchens?

Yes. Polished chrome is a popular finish for bathrooms and kitchens because it looks clean and modern and pairs well with chrome handles, hinges and accessories. Always choose the correct bolt style for the environment and application.

When should I choose a flush bolt instead of a surface bolt?

Choose a flush bolt when you want a more discreet look and the bolt can be recessed into the door edge. Surface bolts are generally quicker to fit and are more visible once installed.

Q: What is the difference between a straight bolt and a cranked bolt?

A straight bolt suits simple surface mounting where the bolt aligns directly with the keep. A cranked bolt is offset, helping alignment where frames or rebates make a straight run difficult.

Where polished chrome bolts work best

Polished chrome is a popular choice for contemporary homes, apartments, and commercial interiors where a brighter finish matches modern handles, hinges, and locks. It can also work beautifully in period properties when you want a crisp, reflective contrast against painted timber or traditional joinery.

Choosing the right bolt for your door or window

If you want a visible, easy-to-use solution, a surface bolt is usually the quickest fit. For double doors, a flush bolt helps keep the inactive leaf secure without visual clutter. If you’re securing French doors or larger openings, an espagnolette bolt provides stronger multi-point control along the height of the door.

Finish matching and consistency

For the best overall look, match your bolt finish to other polished chrome ironmongery in the room (handles, latches, locks, hinges, and accessories). Consistent finishes help the space feel intentional and higher-end — especially in kitchens, bathrooms, and newly refurbished homes.

Understanding Straight, Cranked, Flush and Espagnolette Bolt Styles in Polished Chrome

Polished chrome bolts not only offer a bright and highly reflective finish but also provide robust functionality across various door and window configurations. Here's a quick guide to help you choose:

Straight bolts are ideal for flush-fitting frames. They're surface-mounted and provide simple, reliable security.
Cranked bolts, also known as necked bolts, are designed for doors or windows where the frame is set back. The offset profile ensures the bolt engages cleanly into the keep.
Flush bolts are recessed into the door edge, giving a minimalist, tamper-resistant appearance. Often used on French doors or internal double doors to hold the passive leaf shut.
Espagnolette bolts feature top and bottom locking points activated by a single handle. These are excellent for taller French doors and traditional timber window setups.

Polished chrome is a popular choice across both contemporary and classic interiors, due to its reflective surface and clean look. Whether you're updating security hardware or fitting out a new project, our wide selection of polished chrome window and door bolts offers performance and style in equal measure.

Frequently Asked Questions

What’s the difference between a straight bolt and a cranked bolt?

A straight bolt lies flat on the surface of the frame, while a cranked bolt features an offset to accommodate recessed or stepped frames. Cranked bolts are commonly used on outward-opening doors and windows.

Are flush bolts secure enough for external doors?

Yes, flush bolts offer excellent security when fitted correctly, especially when used in pairs at the top and bottom of French doors.

Can espagnolette bolts be retrofitted?

Many espagnolette systems can be retrofitted, but it depends on the door construction. It's essential to measure accurately and ensure compatibility with existing recesses.
