Manual sanding supply Proline 49140 — abrasive accessory, 1 pc

Proline 49140 is a single-piece manual sanding supply designed as an abrasive accessory for hand sanding tasks. Constructed on a heavy paper backing with a synthetic resin binder and a normal semi-open alumina coating, this sanding item is intended for surface preparation, smoothing and finishing on wood, plywood, MDF, metal and compatible plastics. Supplied as one unit, it suits general-purpose maintenance and restoration work where a versatile abrasive is required.

Advantages

The heavy paper backing provides dimensional stability during manual use while remaining flexible enough to follow contours and edges. The synthetic resin binder secures abrasive grains, enhancing durability and consistent cutting performance. The normal semi-open alumina coating balances material removal and clog resistance, making the product suitable for a range of substrates including wood and metal. Sold as a single unit, it is convenient for small jobs and replacement in sanding kits.

Suitable for

• Hand sanding of wooden surfaces, including plywood and MDF
• Light deburring and surface smoothing on metal components
• Finishing and preparation of painted or bare plastic parts compatible with abrasive action
• Maintenance, repair and small-scale renovation projects

Key specifications

• Backing material: heavy paper
• Abrasive coating: normal semi-open alumina
• Binder: synthetic resin
• Application: wood, plywood, MDF, metal, plastic
• Packaging quantity: 1 piece

How to use

Select an appropriate grit grade (if applicable) for the required level of material removal or finishing. Attach the sanding piece to a compatible manual sanding block or use it by hand, maintaining even pressure and consistent strokes along the surface grain when working on wood. For metal and plastic, use light, controlled passes to avoid excessive heat or deformation. Replace the abrasive when wear reduces cutting effectiveness or when clogging affects finish quality.

Usage recommendations

Use personal protective equipment—dust mask, eye protection and gloves—when sanding. Store the abrasive flat in a dry environment to preserve the heavy paper backing and prevent premature degradation of the abrasive coating. For best results on sensitive surfaces, test on a small area before full application.
