WEMNO Glazing Packers 4mm Grey — 1000 Pack When the reveal is out and the thinner packers are not going to get you there in one piece, the 4mm steps in. It bridges the gap between the fine adjustment sizes and the heavy-duty packers, making it the right choice for frames that need a solid lift without going straight to a 5mm or 6mm. Widely used for packing door frames into masonry openings, levelling window sills with meaningful variation, and handling the kind of out-of-tolerance reveals that older properties throw up regularly. WEMNO flat glazing packers are manufactured from virgin polypropylene to consistent thickness tolerances. The 4mm is genuinely 4mm. Colour coded grey in line with industry convention so anyone on your crew can identify the size instantly without stopping to measure or check. The 100x28mm footprint is the standard used across the UK glazing and fenestration trade. These packers are suitable for toe-and-heel installation of double and triple glazed units, packing window and door frames into reveals, levelling thresholds and sills, and general frame packing across uPVC, aluminium, timber and composite applications. UV stabilised and weatherproof so they will not degrade behind the frame over time. 1000 packers per resealable box. Polypropylene. Weatherproof. Load-bearing. Made to work.
