Match the cap to the base it will cover

The EFB-39 Auto Lock Cap is a closure component, not a complete tray by itself. Provide the base's finished outside dimensions and wall height, plus any rim or insert that affects how the cap sits.

Confirm the locking action and removal

If you already use a tray, send a sample or approved drawing so the cap can be matched rather than estimated from nominal dimensions.

Details to include with a cap request

  • Base dimensions, wall height and board
  • Locking or removal preference
  • Artwork, quantity and finish
  • Matching tray and delivery requirements

Check the cap on the finished base

Which board is used?

Board choice is set around the box size, product weight and handling conditions. The exact grade for the Auto Lock Cap style is confirmed in the specification rather than assumed from a generic GSM figure.

Which products suit auto lock caps?

They suit gifts, cosmetics, chocolates and small items.

What is the minimum order?

The current published minimum for box orders is 100 per size and design. If you need several sizes or artworks, list each one so the quote can confirm how the minimum applies to the Auto Lock Cap style.
