Adjust-2-fit expander frame
All Strongdor steel security doors come with a fully adjustable frame to bridge the gap between the door frame and the rebate. Even if the brickwork is uneven this ensures a perfect fit every time and with the minimal use of sealant. Furthermore, every Strongdor 1500 Series door set includes a comprehensive fixing kit which includes all the nuts, bolts, screws and cover caps you need, as well as full instructions and a pot of colour-matched paint in case of accidents! Follow the steps to see exactly how Strongdor steel security doors always fit perfectly with the minimum of fuss.

Complete installation kit supplied with every Strongdor.
STEP 1: First align the frame into the door opening.
STEP 4: Insert the frame fixers.
STEP 2: Ensure you have a square and tight frame using the adjuster screws.
STEP 5: The fully tightened frame fixers are recessed half way into the frame adjuster screws.
STEP 3: Once the frame is in position, drill through the frame adjuster screws.
Our doors are made from anti-rust, high tensile steel with superior security features, are supplied fully finished to absolutely any RAL or BS colour (not metallics) and carry a three-year warranty, with a five-year warranty on furniture and accessories.
