21mm x 21mm Square Plastic End Plug | 13mm Height | Black LDPE

Designed for finishing exposed square tube ends, this 21mm x 21mm black square plastic end plug provides a neat push-fit closure for box sections, fabricated frames and general tubular assemblies.

LDPE provides the balance of flexibility and durability needed for repeat handling, allowing the plug to compress during fitting while retaining enough strength for everyday tube protection.

Common Applications

  • Finishing square box section frames
  • Closing open tube ends on furniture and display stands
  • Protecting fabricated steel sections during handling
  • Improving appearance on workshop and storage equipment
