  • Standard flat head tube inserts – Ideal for situations where you just want to cap an end or a tube which is at 90 degrees to the floor
  • Domed head tube inserts – Offers a cosmetic enhancement/detail as well as offering an alternative to an angled insert
  • Angled Heads – Pre-set angled ends, perfect for played legs or tubes where an angle is required.
