{"product_id":"shelf-pin-boring-jig","title":"Shelf Pin Boring Jig","description":"A fast, convenient aluminium jig for precise line boring. Features dual hole centre distances of 25mm and 50mm, with four interchangeable bushings (5, 7, 9mm and 1\/4\") for flexible shelf pin installation. Simply match your guide pin to the bushing size, lock with the brass screw, and adjust edge distance using the end stop. Use the drill stop collar to set depth on your first hole, then align subsequent holes by inserting the guide pin into the previous hole while the end stop seats against the edge. Repeat for consistent, accurate hole placement. For opposite-side boring, start from the same reference point to ensure perfectly aligned hole pairs.","brand":"McJING Tools","offers":[{"title":"Default Title","offer_id":51376364093730,"sku":"SPBJ2550","price":25.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0969\/8810\/2946\/files\/Screenshot2026-05-12143807.jpg?v=1778560820","url":"https:\/\/mcjing.com.au\/products\/shelf-pin-boring-jig","provider":"McJING Tools","version":"1.0","type":"link"}
