Handy Hints

Square tube connectors - frame assembly

Handy Hints:
  • ensure the inside of the square tube is clean and smooth. Remove any burrs or swarf
  • use a silicone lubricant, such as CRC, inside the tube end before assembly.
    This will help the shank of the connector to slide into the tube. The lubricant should dry over time.
  • do not use a steel hammer to drive in the connector because it will damage the Nylon outer.
    If required, use ONLY a hard rubber mallet or soft Nylon / PU head hammer.
