Winkhaus Thunderbolt | FIVE-Point Locking

Multi-Point Locking System with 5 Deadbolts – as standard.

The Winkhaus ThunderBolt multi-point door locking system combines high security with extremely easy installation.

Incorporating twin deadbolts in the upper and lower positions this locking system has 5 DEADBOLTS as standard. Each deadbolt is 20mm long and 8.5mm thick giving very high security and peace of mind – easily passing the rigours of PAS24.

Unlike conventional hook locking systems the ThunderBolt™  has been especially designed to offer up to 50% greater fitting tolerances. This allows for a greater variation in airgap dimensions when the door is installed.


Here’s 8 reasons to consider the Winkhaus ThunderBolt™ 5 for your next Door installation;

  1. Twin 20mm throw deadbolts for a total of 5 high security locking points giving very high security and peace of mind.
  1. High security system that easily passes the rigours of PAS23/24 and EN14351-1 2006 security standards when fitted into a door. Approved by the Police ‘Secured by Design’ security initiative – an essential requirement of the Association of British insurers.
  1. High performance gearbox tested to 100,000 cycles. The sprung gearbox offers the lowest possible operating forces and helps prevent handle ‘droop’.
  1. Heavy duty steel keeps manufactured using high grade steel, plated to comply with Grade 4 corrosion resistance requirement of BS EN1670 European Standard.
  1. Fully adjustable system designed to increase fitting tolerances by up to 50% with a +/- 2mm adjustment in the keep for variations in weather seal compression and door misalignments after installation.
  1. Compatible with industry standard handles and also with the Winkhaus Palladio™ and DDA handle range. Designed to meet PAS23/24 Security standards with the Winkhaus XR6-51 Kitemark profile cylinders (KM531333) and Armorshield™ cylinder guard.
  1. Superbly engineered and manufactured in Germany from the highest quality materials and components.
  1. Lifetime adaptability interchangeable with the ‘Winkhaus family of locks’ with exactly the same routing details as the Winkhaus Cobra™, Trulock+ and Automatic AV2+ range of locks.
