Introducing The Coniston
Existing locking solutions available for oversized doorsets can be crudely engineered, using poor-quality materials and imprecise manufacturing techniques, resulting in difficult and unreliable operation.
These doorsets demand a robust, dependable locking system that enables the easy movement of machinery and vehicles in and out of the premises, without compromising the overall strength and performance of the building's security.
Oversized speciality doorsets are utilised worldwide to secure everything, from sealing doorsets for aircraft hangars to blast-resistant doorsets for oil refineries. Whilst each building has unique requirements, they all share a common requirement for high levels of pressure resistance.
Introducing the Coniston by Surelock McGill—a purpose-built solution addressing these limitations in high-performance locking systems for oversized doorsets. Its robust mechanical design and stainless-steel construction set it apart from the competition.
The Coniston is a highly reliable, heavy-duty, manually operated bolting system for oversized swing and sliding doorsets. This stainless steel, surface-mounted system offers a choice of 90 or 180-degree handle rotation, increasing bolt engagement and suitability for blast pressures, acoustics, floods, pressurized or uneven pressure, and sealing doorsets.
Designed for over-height doors, the Coniston offers a flexible range of bolt shapes, sizes, and throws to meet each project's bespoke needs.
Large Bolt Throw
for high levels of engagement for blast pressure
Adjustable Roller Strike
for increased control of seal for acoustic & RF doorsets
For acoustic and RF doorsets, fully securing the door is vital for peak performance. The Coniston's top bolt can be paired with an adjustable roller strike to enhance the control and sealing capability for the large doorsets, optimizing their performance.

The Coniston provides a standard package for doors up to 2.7 m (9 ft), extendable to 7.3 m (24 ft) with optional tube extensions. Utilising additional tube guide brackets, the Coniston offers a dependable, high-quality locking solution, regardless of door size, for robust security and reliability.
