Staples for Staple Gun KAN-therm Spinki U55 14–18 (55 mm) pack 25 pcs — 500 pcs total

KAN-therm Spinki U55 staples are U-shaped metal fasteners designed for use with compatible staple guns. Each block contains 25 staples sized for 14–18 mm material thickness with 55 mm leg length; the full pack includes 20 blocks for a total of 500 staples. These staples are intended for mechanical fixing tasks where a U-shaped staple profile provides secure retention through thin boards, membranes, insulation materials, construction textiles and similar substrates.

Advantages

These staples provide a consistent U-shaped profile and uniform leg length to ensure even penetration and holding force when driven with a staple gun. The 55 mm leg length allows for fastening through thicker insulation or multiple layers while maintaining a low profile on the surface. Packaged in blocks of 25 for quick loading and handling, the full pack of 500 reduces the need for frequent resupply on site. The metal construction offers reliable mechanical grip in common construction substrates.

Suitable for

• Fixing thermal insulation boards and rolls
• Securing vapor barriers and waterproofing membranes
• Attaching construction textiles and geotextiles
• Fastening lightweight panels to timber or light framing
• General U-shaped staple applications in building and renovation work

Key specifications

• Staple shape: U-shaped
• Material thickness compatibility: for 14–18 mm material
• Leg length: 55 mm
• Quantity per block: 25 staples

How to use

Select a staple gun compatible with U-shaped staples sized for 55 mm leg length and designed for 14–18 mm material thickness. Load one block of 25 staples according to the tool manufacturer’s instructions and position the staple gun squarely over the material to be fixed. Drive staples at regular intervals to achieve uniform fastening, ensuring the substrate beneath provides sufficient support for the staple legs. When a block is spent, reload with the next block until the pack is depleted.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses and gloves. Check that the staple gun settings (if adjustable) match the staple dimensions and substrate type. For applications in damp or corrosive environments, verify compatibility of the staple’s metal finish with local conditions or consider additional corrosion protection measures. Store remaining staples in a dry place to prevent surface oxidation.
