Manthorpe 50mm -100mm Multi-Width Cavity Closer 2.44m Length - Pack of 6

The Manthorpe WCMulticor is a multi-width TDI cavity closer designed to suit standard cavity widths between 50mm and 100mm in a single product, providing both a thermal break at window and door reveals and an effective vertical DPC barrier at the jambs. Its double flanged profile is produced from a single PVCu extrusion with a 20mm EPS insulation insert (K-value 0.030 W/mK), achieving the required thermal resistance at the reveal when frames are fixed with a minimum 30mm overlap into the cavity. Groove guides allow quick and accurate on-site cutting to suit various cavity widths without specialist tools. BBA certified (Certificate No. 96/3226) and suitable for single person installation. Supplied in 2.44m lengths, sold in packs of 6.
