The Thunderbolt Multipoint Lock is an ideal solution for entrance doors and other external doors in domestic settings requiring a high security yet cost effective and versatile locking system. The chamfered twin deadbolts are designed 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. This Short Door variant has a lowered top bolt position and cropable square end faceplate for shorter doors from 1625mm high.
Lift-Lever Operation: The central deadbolt and top/bottom twin deadbolts are thrown by lifting the door lever handle. The door is then locked by operation of the lock cylinder barrel. Unlocking of the door is by reverse action. 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).
This lock is supplied WITHOUT centre strikeplate or bolt keeps. Suitable strike and keep sets can be found in the 'Related Items' section below.
Important: Winkhaus locks are finished with a corrosion resistant electroplating. However, care should be taken when fitting to highly acidic woods such as oak and accoya or in extreme coastal locations. Contact between the lock and bare timber should be avoided. Where possible, timber should be painted or varnished prior to fitting the lock especially under and around the faceplate. For best results we recommend the use of our 3 Part Corrosion Protection Kit.
Winkhaus multipoint locks are supplied WITHOUT fixing screws. Suitable fixings can be found in the 'Related Items' section below.
This lock is site reversible to suit left hand or right hand applications.
For optimum security this lock should be fitted with a TS 007 3 Star cylinder (see our ULTION Maximum Security range).
Lever handle furniture MUST be of a type that allows the handle to be lifted. Handle backplates should be compatible with the lock centres measurement and fixing centres measurements. Please refer to the relevant technical drawings.
To keep this multi-point lock in optimum working condition we recommend a once yearly application of light machine oil (3 in 1) to all moving parts. Wipe clean with an oil impregnated cloth.
