Uniform-hole layout

The same hole diameter repeats across the plate. For a conduit group using the same outside diameter; specify the required clearance. Send a dimensioned drawing for feasibility and pricing review.

Mixed-diameter layout

Hole diameters vary to match the conduit schedule. For a drawing with more than one conduit size; identify every opening. Send a dimensioned drawing for feasibility and pricing review.

Compact or larger array

Hole count, rows, columns and plate outline change. Specify the complete pattern and edge distances; do not scale a photo to obtain dimensions. Send a dimensioned drawing for feasibility and pricing review.

Electrical conduit arrays

Use a repeated hole pattern to organise parallel conduits for a planned duct-bank layout. Match the spacer to the project drawing before assembly.

Plan for
Conduit outside diameters, hole clearance, separation and the specified support arrangement.

Communications conduit layouts

Prepare a flat spacer plate for a grouped communications conduit run. Set out each hole from the drawing, including any reserved positions.

Plan for
Conduit count, rows and columns, hole sizes and required plate thickness.

Mixed-diameter project layouts

Request a plate with different hole diameters where the project drawing calls for different conduit sizes. Identify each opening so the pattern is unambiguous.

Plan for
A hole schedule, centre locations, edge distances and quantity for each plate design.

Before you order

Match the material
to the project.

A hole pattern defines the plate geometry. Your project design defines conduit separation, support intervals and installation requirements. Send that drawing so the spacer can be reviewed against it.

Prepare the details

Plan the size.
Check the application.

Define each conduit and hole

List the actual conduit outside diameter, required hole diameter or clearance, and the quantity of each opening. Nominal conduit size alone does not define the finished hole.

Dimension the complete plate

Specify the plate outline, thickness, hole centres, edge distances and units. State whether a spacing dimension is centre-to-centre or the clear gap between conduits. Include any tolerances required by the design.

Send the quote package

Include the dimensioned drawing, quantity per plate design, intended use, delivery location and required date. Pricing varies with the dimensions, material thickness, hole pattern and quantity; Supply Kings confirms feasibility, price and timing. S1

Handling & care

Check fit before the main assembly

Compare the supplied plate with the approved drawing and check the conduit fit. Keep openings free of debris; report damage or a mismatch before installation.

Follow the project installation details

Use the project specification for support intervals, restraint, lifting and installation. The plate layout does not establish a structural rating or the required spacing along a conduit run.

Other details to confirm

Confirm the supplied specification

Thickness, colour, grade, tolerances, quantities and timing are agreed by quote. Any required test reports, approvals or application-specific documentation must be identified with the request. S1
