SELECTION AND SPECIFICATION PROCEDURESelection and SpecificationThere are two main starting points in practice.A. Cables or pipes known, no frame.The ideal way, is when the numbers anddiameters of cable or pipe are known, inadvance of ordering the frame. The procedureshould then follow route A.B. Frame already installed.However, if a transit frame and cables orpipes are already installed, and sealingspecifications are to be determined later,follow route B.No frame, cable or pipe requirements to beadvised in future.If a frame only is required, and all cable/piperequirements are to be advised at a later datein the contract, install as large a frame as ispossible, and fill it with blank blocks.Modular Cable/Pipe Tolerant BlocksIn the Block Selector Table below, the firstcolumn indicates the module size, secondand third columns indicate minimum andmaximum diameters of cable or pipe whichcan be accommodated by each block.Blank Filler blocks are suffixed ‘0’e.g. 15/0 20/0 etc.Code NumbersFor ordering purposes block code numbersare made up from the numbers in columns 1and 2 and are indicated in column 5. i.e. A40 module block capable of accommodatingcable/pipe from 28mm diameter up to 31mmdiameter is denoted 4028. A HF prefixdenotes zero Halogen blocks.NOTE: Two insert blocks are required foreach cable or pipe.Selection and Specification Procedure120 x 60 x 5 Packaging Strip 1120 x 60 x 10 Packaging Strip 1A- Cables/pipes known, no frame B- Frame already installedSTART1.
