The Winkhaus Thunderbolt KTA Key/Thumbturn Multipoint Lock is an ideal solution for single entrance doors and other external doors in domestic settings requiring a high security yet cost effective and versatile locking system and has been especially designed with increased tolerances for door installers. An excellent choice for doors where lever handles are either not required or are of a type not suitable for lift-lever operated locks. This Standard variant has a radiused end faceplate and is suitable for normal height doors up to 2105mm.

Supplied here in lock only format excluding strikeplates and keeps. Individual strikes and keeps can be purchased via the relevant product link in the "Related Items" section below.

  • Key/Thumbturn Operation:
    All bolts are thrown and retracted by operation of the lock cylinder barrel thus negating the need for lever handle furniture. Depending on the requirement, lock cylinders can be key and turn type (external key/internal thumbturn), double cylinder (key both sides) or single cylinder (key one side only). Lever handles can be fitted in full or half sets if required and will withdraw the central latchbolt only.
  • High Security:
    Thunderbolt locks have been tested in all frame materials to PAS23/24 Enhanced Security standards and are approved by the Police 'Secured by Design’ Security initiative and by the Master Locksmith Association’s Sold Secure Scheme.
  • 20mm Throw Nickel Plated Twin Deadbolts:
    The specially designed twin deadbolts are chamfered to allow a high degree of fitting tolerence for door installation. In addition, the deadbolt shape provides low operating forces and helps doors achieve a higher level of weather performance.
  • High Performance Central Gearbox:
    Tested to 100,000 cycles the sprung gearbox offers the lowest possible operating forces and helps prevent handle droop. Nickel plated sprung latchbolt and 20mm throw nickel steel deadbolt provide maximum strength in the centre of the door.
  • Corrosion Resistant:
    Winkhaus locks have a protective surface coating in excess of EN 1670 : 2007 Grade 4 which is designated as ‘Very high corrosion resistance’
  • Weather Seal Compression Adjustment:
    Enhanced bolt design and adjustment in the keeps provides low operating forces. With ± 2mm adjustment it is possible to adjust for misalignment of the door during and after installation.

For optimum security this lock should be fitted with a TS 007 3 Star cylinder (see our ULTION Maximum Security range) or a TS 007 1 Star cylinder with 2 Star cylinder guard (see our Adapta Prime High Security range).

If required, lever handle furniture can be self-sprung or unsprung either on backplate or on rose with seperate cylinder escutcheons. Handle backplates should be compatible with the lock centres measurement and fixing centres measurements. Please refer to the relevant technical drawings.

One Thunderbolt KTA Standard Variant multipoint lock as described. Strikeplates and keeps should be ordered seperately if required.

This multipoint lock is normally available from stock. If we are temporarily out of stock you should allow 10 - 14 working days for despatch.
