These maintain theopenings through the walls and floorsand add to the finished appearance of theinstallation.4.The mastic can be applied to front or rearof the frame dependant on the installation,see Fig.7.5.The frame can now be placed over itsfixings and the fasteners tightened to clampthe frame to the wall. In tightening the fixturesthe mastic should be extruded out of thedecreasing gap between frame and structure,any excess should be removed and disposedof. When tightened up to the requiredamount, the mastic should be faced off to theframe leaving a fillet of mastic around theinternal and external edges of the frame.See Fig.7 above.Fig.9It should be noted that the backing plates donot add to the fire resistance of a transitassembly and should not be used to stop firespread in cavity walls.Backing plates are produced in standardlengths for wall thickness of 60mm to200mm for sizes 2, 4, 6 and 8 framesplus multiples thereof, but specials can bemade.Please state thickness of wall when ordering.Installations and ApplicationsThere are several methods whichcan be used to install HawkeFrames, each methodgiving an inspectable professionalfinish to any cable penetration.When fixing frames toconcrete/brick type structures careshould be taken if usingexpanding type fixings as theycould burst into the aperture.For Hawke Frames which are castinto a wall or floor it isrecommended that a HawkePolystyrene Mould is used.Frames and moulds requiresupport to ensure that the correctposition is maintainedwhilst the concrete is beingpoured.
