All Groke doors are engineered around a high quality multi-point locking system, and a multi-chamber, thermally separated frame with one of the largest wall thicknesses in the market.
Every Groke door has two stainless steel bolt pins on the hinge side of the door that prevent the door from being levered out.
Groke doors also feature a long, double European lock cylinder, that will leave any would-be lock-picking burglar scratching their head.
MULTI POINT LOCKING SYSTEM
STANDARD Multi- point Three Bolt Hook Locks.
Multi-point locking has obvious security benefits, but also contributes significantly to energy savings and exterior noise re- duction by creating a super tight seal all the way around the perimeter of the door.
