From The Anvil BZP Winkhaus Thunderbolt Espag Locks

This collection features the Winkhaus Square Ends Thunderbolt espagnolette lock in BZP, designed for use with 92mm centre espagnolette locking handle sets. The mechanism uses solid twin deadbolts positioned at the upper and lower points to provide positive locking on the door.

Length, door-height range and what’s included

The option shown in this family is the 2100mm lock, specified as suitable for doors with a minimum/maximum height of 1625mm to 2105mm. Compared with conventional hook locking systems, this Thunderbolt design is stated to offer 50% greater fitting tolerances, which can help when setting and aligning the system on the door.

Please note that a Euro cylinder is required to complete the locking set and is not included, so it needs to be purchased separately. The finish available across this collection is BZP.
