Concrete Spacer Block Mould Buyer Guide

Spacer block mould orders are usually driven by rebar cover thickness, mould 1-out-N count and whether the mould is for sloped, saddle, bar strip, plum-blossom or round disc applications.

Typical spacer mould types

  • Spacer block moulds: square, conical, sloped and U-shaped blocks for general cover.
  • Saddle spacers: used in slab-on-grade and foundation work to support rebar mesh.
  • Bar strip and plum-blossom spacers: for narrow rebar or specific cover thickness requirements.
  • Round disc and slot insert spacers: for vertical rebar in columns and walls.

Project drawing checklist

For spacer block moulds, the key parameters are the cover thickness, finished block dimensions and the 1-out-N count. A sample photo or marked drawing helps confirm orientation and demoulding direction.

  • Specify the required cover thickness (e.g. 20mm, 30mm, 50mm).
  • Confirm the finished spacer dimensions and 1-out-N count.
  • Mark whether the mould is for horizontal slab or vertical rebar use.

Spacer Block Mould FAQ

Can you make custom spacer moulds from drawings?

Yes. Send a sample photo, dimensions or marked drawing. We can review the profile and suggest a mould structure.

Can I order different spacer types in one shipment?

Yes. Mixed-SKU orders are common for construction projects where multiple spacer types are required together.

Are these moulds only for rebar cover?

No. Spacer block moulds are also used for ballast blocks, concrete test specimens and other precast concrete elements.
