Introducing The Coniston
Existing locking solutions for oversized doors can be crudely engineered using poor-quality materials and imprecise manufacturing techniques resulting in difficult and unreliable operation.
These doors demand a robust and 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, specialty doors are used worldwide to secure everything from aircraft hangars to blast-resistant doors for oil refineries. While each building has unique requirements, they all need a dependable locking solution that ensures that their doors are properly secured and sealed every time.
Introducing the Coniston by Surelock McGill—a purpose-built, high performance locking solution for oversized doors. 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 doors. This stainless steel, surface-mounted system offers a choice of 90 or 180-degree handle rotation which increases bolt engagement to provide resistance to the highest blast pressures, acoustic abatement, or RF mitigation.
Designed for over-height doors, the Coniston offers a flexible range of bolt shapes, sizes, and throws to meet each project's custom needs.
Large Bolt Throw
for high levels of engagement for blast pressure
Adjustable Roller Strike
for increased control of seal for acoustic & RF doors
For acoustic and RF doors, 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 oversize doors, thus optimizing their performance.
Custom Tube Lengths
for oversized doors - optional extensions up to 24 ft
The Coniston provides a standard package for doors up to 9 feet but can easily be extendable 24 feet and even beyond with optional tube extensions. Regardless of the door size, the Coniston is a dependable, high-quality locking solution.
