Siafast 6 Inch Soft Low Profile Hook And Loop Backup Pad

Description

Siafast backup pad SIA7486.5440.0000 is a 6 inch non-hole hook and loop pad for shops using Siafast abrasive discs on compatible sanders. The master product data lists a 3/8 inch thick soft low-profile pad with 5/16-24 thread, giving operators a flexible support surface for contour work, finish sanding, and disc changes.

Siafast backup pad Benefits

• Hook and loop face supports quick abrasive disc changes during multi-grit sanding steps.
• 6 inch diameter matches common DA and orbital sanding workflows.
• Soft low-profile construction helps the disc follow slight curves and surface transitions.
• 5/16-24 thread fits compatible sanders that use that spindle format.
• Non-hole design works with matching no-hole discs and general shop sanding setups.

A backing pad is a wear item, and replacing it at the right time helps keep sanding results consistent. Worn hooks, damaged foam, or a pad that no longer runs flat can reduce disc hold, leave uneven scratch patterns, and slow finish work.

Where Siafast backup pad Fits

• Countertop fabrication sanding on solid surface, stone-adjacent trim, and shop fixtures.
• Cabinet and wood finishing steps using 6 inch hook and loop abrasive discs.
• Paint, primer, and filler preparation where a softer support pad is preferred.
• General manufacturing cells that keep multiple pads by grit family or material.
• Sign and display shops that sand mixed plastics, composites, and coated surfaces.

Use and Replacement Notes

Match the pad thread to the sander before installation and check that the pad seats squarely. Inspect the hook face before each sanding sequence. If discs start slipping, lifting at the edge, or leaving chatter marks, replace the pad before increasing tool pressure.
