Euro Profile V10 Single Cylinder 50mm – Keyed to Differ

In architectural ironmongery, a single cylinder is utilized when the locking mechanism is only accessible from the exterior.

Key Benefits of the 50mm Length

• Standard Reach: At 50mm, this 50mm euro profile single cylinder is slightly longer than the basic 40mm or 45mm half-cylinders. This extra length is often required for modern composite gates or garage doors with decorative external handles where a shorter barrel would be recessed too deeply.

• Adjustable Cam Performance: Most high-quality 50mm single cylinders feature an adjustable 8-position cam. This allows the internal actuator to be rotated to match the specific “throw” required by different brands of shutter locks or panic hardware.

• Enhanced Tamper Resistance: Because there is no keyway on the interior, there is no “through-hole” for an intruder to exploit using wires or specialized picking tools from the inside of the garage or warehouse.

• Debris Protection: Ideal for external environments. The solid internal side prevents rain, dust, and insects from blowing through the lock cylinder and into the building or mechanism.

Precision Sizing: The 40/10 Offset

A 50mm euro profile single cylinder is measured from the center of the fixing screw to each end. Because the “blind” side is a fixed mechanical standard (10mm) to house the cam and fixing point, a 50mm cylinder is an asymmetric split.

Pro-Tip: Always measure from the center of the locking screw toward the outside face of the door. If that distance is 40mm, this is the correct cylinder for your installation.

Recommended 50mm Single Cylinders

For high-use commercial shutters or premium garage doors, the 50mm euro profile single cylinder is an exceptional choice. Its 10-pin system provides superior pick resistance, making it a favorite for industrial units and high-end residential garages.

Installation Pro-Tip: The “Cam Alignment”

When installing a 50mm euro profile single cylinder into a panic bar or shutter, you may find the key won’t turn. This is often because the internal cam is not in the correct starting position.

1. Use the key to rotate the cam until it aligns with the internal actuator of your lock.

2. Once aligned, the cylinder should slide in effortlessly.

3. Tighten the fixing screw, then test the operation with the door open to ensure the deadbolt throws and retracts smoothly.

A 50mm Euro Profile Single Cylinder (often referred to as a 40/10 Half Cylinder) is a specialized security barrel designed for doors that only require key access from one side. This makes it the industry standard for garage doors, rolling shutters, garden gates, and surface-mounted panic bars, where an internal keyway is either unnecessary or physically obstructed.

By featuring a “blind” internal face, this cylinder provides a clean, tamper-proof finish on the protected side of the door.
