Product Details
A tire repair scraper forms part of the preparation-tool assortment used around the tire inner liner. AUTOWIN lists four catalogue models for pre-buff inner-liner cleaning: STR-21/1, STR-21/2, STR-21/3 and STR-22. The first three are identified by green, blue and black handles respectively; STR-22 is described as a blade-style inner liner scraper.
Use these model references to organize your purchasing list, while checking the working end separately. Handle colour identifies the listed variant but does not establish blade width, edge material or cutting performance. The current table does not state dimensions, so obtain the necessary blade and overall-tool measurements when matching an existing workshop item.
For distributors, compare the preparation task and the available working space before choosing a model mix. A hand scraper, a skiving knife and a patch stitcher perform different roles within a repair-tool range. Keep their descriptions and ordering references separate so a replenishment order supplies the intended tool rather than a similar-looking item.
When requesting wholesale pricing, state quantities by STR reference and include an edge-profile photograph or drawing if dimensional matching is important. Add the required packing unit, destination and labelling details. The selected scraper should suit the approved repair process and surface; the page does not establish a universal removal method or suitability for every rubber material. Individual STR-21 product listings can be reviewed alongside this series table before approving the order specification.

Frequently Asked Questions
Which handle variants are listed in the STR-21 scraper range?
The catalogue identifies STR-21/1 with a green handle, STR-21/2 with a blue handle and STR-21/3 with a black handle. STR-22 is listed separately as a blade-style inner liner scraper. Confirm the required working-end dimensions for each reference.
Does handle colour confirm a different blade size or material?
No. Colour distinguishes the catalogue entries but does not provide blade dimensions or edge-material specifications. Request these details against the selected model when matching a replacement tire repair scraper.
Where can buyers review the individual STR-21 scraper listings?
Review the <a href="https://autowinindustrial.com/products/tire-service-products/tire-repair-tools/rubber-scrapers/autowin-tire-repair-rubber-scraper-str-21-1/">STR-21-1 rubber scraper</a> and <a href="https://autowinindustrial.com/products/tire-service-products/tire-repair-tools/rubber-scrapers/autowin-tire-repair-rubber-scraper-str-21-2/">STR-21-2 rubber scraper</a>. Keep the catalogue reference and the individual product reference together in the enquiry.
What should a scraper replenishment order specify?
State the STR model and quantity, the intended preparation task, any required edge profile or dimensions, and the packing unit. Include a sample reference when the new order must match tools already used in a workshop.
