Oval Knob Locking Espagnolette Bolt for Up to 8.5′ High Doors & Windows: Secure Elegance Meets Modern Engineering

 

Introduction: Where Design Meets Durability in Door Security

When it comes to tall doors and windows — especially those over 8 feet high — security, functionality, and aesthetics must work hand-in-hand.

Enter the Oval Knob Locking Espagnolette Bolt — a timeless piece of precision hardware that combines architectural beauty, superior locking strength, and effortless usability.

Designed for doors and windows up to 8.5 feet high, this espagnolette bolt offers the perfect balance of form and function, making it a favourite among architects, interior designers, and homeowners who refuse to compromise on quality.

Whether you’re securing elegant French doors, tall patio windows, or bespoke wooden frames, this bolt offers a smooth locking mechanism, robust stainless steel construction, and visual sophistication that elevates every space it protects.

1. What Is an Espagnolette Bolt?

An espagnolette bolt is a multi-point locking system that secures doors or windows from top to bottom using a single handle or knob mechanism.

When you turn the oval knob, metal rods (shoot bolts) slide into the top and bottom of the frame — creating three-point locking strength that’s nearly impossible to force open.

In Simple Terms:

  • Turn the knob → Locks both ends simultaneously.
  • Result: Reinforced vertical security with minimal effort.

Where It’s Commonly Used

  • Tall French doors
  • Casement windows
  • Bi-fold doors
  • Cabinet-style double doors

 

2. The Oval Knob Advantage: Designed for Style and Control

Unlike traditional lever-operated bolts, the oval knob design provides a sleek, ergonomic grip that enhances both comfort and control.

Key Benefits of the Oval Knob Design

  • Smooth operation: Turn and lock in one fluid motion.
  • Space-saving: No protruding handles or catches.
  • Timeless aesthetics: Complements modern, classic, and heritage interiors alike.
  • Custom finishes available: Polished chrome, brushed nickel, antique brass, or matte black to match any décor theme.

This blend of function and sophistication makes it the preferred choice for luxury interior designers and architectural hardware specialists across the UK and beyond.

 

3. Precision-Engineered for 8.5′ High Doors & Windows

The Oval Knob Locking Espagnolette Bolt isn’t your average lock — it’s engineered to perform flawlessly on doors and windows up to 8.5 feet high.
