An incredibly important part of any bi-folding door system is the locking mechanism. Guaranteeing safety and security for homeowners is essential so they have peace of mind their homes will be well protected against unwanted intruders. In fact, the type of lock that’s used will no doubt be a determining factor as to whether or not the homeowner invests in the bi-fold.

The importance of an efficient aluminium bi-fold door locking system

Efficient locking mechanisms play a fundamental role in ensuring bi-folding systems are secure which, as we mentioned above, is a must-have for homeowners.

A robust and durable lock will not only properly protect any home, and its belongings, from unwanted intruders but it will also be able to withstand the elements and resist corrosion which is incredibly important.

As leading bi-fold hardware specialists, we understand exactly what’s needed to design and manufacture a quality bi-fold door lock. In fact, we’ve developed our own locks which have been specially made with both the fabricator and the homeowner in mind.

Spotlight on the Debar Robus shoot bolt lock

Our Robus shoot bolt lock is a heavy duty steel lock that works effectively with intermediate panels of a bi-fold door. It provides two points of engagement as the connecting rods shoot the bolts into the top and bottom tracks which efficiently secures the doors.

Used in either residential or commercial applications, the Robus shoot bolt lock has high grade corrosion protection and works with any configuration of bi-fold to have access from both inside and out – with or without a key or cylinder.

To ensure the shoot bolt works on a number of different bi-folding systems, we’ve designed the lock so that fabricators have the option to include cover caps as well as shoot bolt ends and guides.

In terms of technical specification, the Robus Shoot Bolt also features:

  • 8mm and 10mm thread versions as standard
  • M5 screw holes inside the face for a cover
  • The handle turns 90 degrees to fully operate
  • Shoot bolt throw of 23mm
  • 7mm spindle hold
  • Handle screw centres at 43mm
