£2,000 Guarantee
Rockdoor lock cylinders are burglar proof. A TSOO7 3 star rating, SS 312 Sold Secure Diamond Standard and Secured by Design accreditation see to that, plus a £2,000 security guarantee.
Forced Entry
Rockdoors are designed for strength, it is in the DNA. For over 25 years, they have led the way in composite door development to ensure their doors protect homes and families from unwanted intruders and forced entry.
Hook up with Rockdoor
Strong sintered steel multi point hook locks with a 25mm throw, securely attach the door to the frame to ensure it cannot be forcibly opened by burglars whilst ensuring a better sound and weatherproof seal.
Glass Leading Security
Rockdoors feature S Glaze technology, meaning your glass is locked into your door for life, for added security. It also means no glazing cassettes are used which are prone to fading and discolouration.
