TBR tubes are made in 1 m lengths with diameters of 1.5, 2.5, 3.5, 6, 8 and 10 mm, black and transparent (index T). BOLTBR kits have 8 cm lengths: BOLTBR-1 has 10 tubes in white and black, Ø3.5, Ø5 and Ø13 mm, and BOLTBR-2 has 18 tubes in red, blue and black, Ø3.5, Ø5 and Ø7 mm.
How to choose
Choose the connector by the wire cross-section and the sleeve colour. For 0.5–1.5 mm² take the CTR15, for 4–6 mm² the CTR60, for 10–16 mm² the CTR160. Select the tube diameter to suit the size of the joint. The sleeve material, shrink temperature and shrink ratio are not stated in the available manufacturer data, so they should be checked before purchase.
