Ensure that the TW Pro MB Offset Locking Band is installed in conjunction with 15/30/45 degree bends, replacing the standard locking bands where extended offsets are required. When installing, verify that the offset length does not exceed 250mm between bends unless additional support is provided. For offsets longer than 250mm, install an extra wall band or appropriate support. Fixings must be robust to support free standing offsets of up to 1.5m. Always maintain a minimum distance of 50mm to any combustible material. Refer to manufacturer guidelines and consult a professional if uncertain about installation procedures. Safety first: ensure proper structural anchoring and follow local building regulations.
