Gap Feeler Tape INSIZE 0.25 mm x 5 m model 4621-25

INSIZE gap feeler tape 0.25 mm x 5 m model 4621-25 is a flexible measuring tape designed for accurate inspection and measurement of narrow gaps and clearances. With a constant thickness of 0.25 mm and an extended 5-metre length, this tape allows access to confined areas and long runs where a conventional feeler gauge or ruler would be impractical. The product is intended for use in workshops, maintenance, quality control and inspection tasks that require repeatable, straightforward gap measurement.

Advantages

The flexible construction enables the tape to conform to curved surfaces and reach into tight spaces while maintaining a consistent thickness for reliable measurement. Its 0.25 mm thickness provides a simple go/no-go reference for clearances and fits where a single, precise value is needed. The 5 m length reduces the need for joins or extensions when measuring along long seams or assemblies. The tape is lightweight and easy to handle, supporting efficient inspection workflows without specialized fixtures.

Suitable for

• Measuring narrow gaps and clearances in mechanical assemblies
• Inspection of joints, seams and panel fitment in automotive and industrial applications
• Maintenance checks where access is limited or surfaces are curved
• Quality control processes requiring a consistent 0.25 mm reference

Key specifications

• Thickness: 0.25 mm
• Length: 5 m
• Form factor: flexible tape for access to tight or curved areas
• Primary use: gap and clearance measurement
• Typical environments: workshop, maintenance, inspection

How to use

Insert the tape into the gap or along the clearance to be checked, ensuring it seats fully without excessive bending that would alter its effective thickness. For best results, lay the tape flat against one surface and verify contact along the length you wish to measure. If the tape slides through freely, the gap exceeds 0.25 mm; if it meets resistance, the clearance is at or below 0.25 mm. Use steady, controlled motion when probing to avoid damage to sensitive surfaces.

Usage recommendations

Keep the tape clean and free of debris to preserve measurement accuracy. Store the tape flat or loosely rolled to prevent permanent kinks. When inspecting painted or delicate surfaces, use gentle contact and consider a protective film to avoid marking. Replace the tape if it shows signs of wear or permanent deformation that could affect thickness.
