Collar extensions

What they are and when to use them

  • Adds 50 mm of height. Each ring stacks onto the collar, or onto another extension, to match a thicker slab.
  • For slabs deeper than 250 mm. The standard collar is 250 mm high; add extensions where the slab is deeper.
  • One per collar size. SELFC-65EXT, SELFC-110EXT and SELFC-150EXT match the H65S, H110S and H150S.
  • Cast in with the collar. Fitted before the pour as part of the cast-in assembly, not added afterwards.
  • Part of the certified system. Extensions are covered by the collar’s LPCB certification, not tested separately.
