GROKE Security Door Features

​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.
