As a hand tool, it is small enough to carry in a repair kit, yet practical enough for detailed regulation work on acoustic pianos. Its main job is to act as a piano tuning tool and measuring tool for checking opening positions with stable, repeatable results. When you are working inside a piano and need to confirm spacing or movement, having a dedicated gauge helps you avoid guesswork and keeps adjustments more consistent from a single key to the next. The adjustable measuring gauge design adds real flexibility, especially when different instruments or mechanisms call for slightly different setup points. Instead of forcing a one-size-universal approach, you can position the tool to match the task and work more efficiently. For busy technicians, that means less time spent rechecking and more time getting the regulation successful immediately. Whether you are servicing a workshop piano, doing a fine-tune at a customer’at a client's location, or handling routine maintenance, this piano regulation gauge is built to support careful, controlled work and a more even end result.\n\nOption: Fixed Door Gauge","category":{"slug":"music","label":"Music & Luthier","google_path":"Arts & Entertainment > Hobbies & Creative Arts > Musical Instruments"},"product_category":"Arts & Entertainment > Hobbies & Creative Arts > Musical Instruments","brand":"SuntekStore","condition":"new","price":"17.89 USD","price_amount":"17.89","currency":"USD","price_valid_until":"2026-10-31","tax":"US sales tax calculated at checkout (prices exclude tax)","availability":"in_stock","inventory_quantity":20,"max_quantity_per_order":10,"shipping":"US:ALL:Standard Shipping:12-22:0.00 USD","delivery_days":{"min":12,"max":22,"unit":"calendar_days_from_order","handling_business_days_max":4},"estimated_delivery":{"if_ordered_on":"2026-10-01","earliest":"2026-10-13","latest":"2026-10-23"},"ships_to":["US"],"shipping_cost":"0.00 USD","return_window_days":30,"return_policy":{"window_days":30,"window_starts":"delivery","condition":"unused, in original packaging","return_shipping_paid_by":"customer (we pay if the item is damaged, defective or not as described)","refund_method":"original payment method","refund_within_business_days_of_receipt":5,"how":"https://suntekstore.com/contact/ with the order number","url":"https://suntekstore.com/returns/"},"package_dimensions_cm":[17.0,5.0,2.0],"weight_g":100.0,"material":"Metal","package_includes":"Fixed Door Opening Measuring Tool ×1","product_dimensions_cm":[15.0,2.5,0.5],"specifications":[{"name":"Instrument type","value":"Piano"},{"name":"Product type","value":"Door opening gauge tool"},{"name":"Use","value":"For technicians"},{"name":"Feature","value":"Precision regulation gauge"}],"image_link":"https://suntekstore-img.sfo3.digitaloceanspaces.com/p/3b/3b253def01c98e4025bffb7fb301920e68b2db5a.jpg","additional_image_link":["https://suntekstore-img.sfo3.digitaloceanspaces.com/p/d2/d248b6cc1652abe63fd8ae2469cf68f9ca936f26.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/d1/d11944e7532158228a3d9484ec1b7a2dc34e0c85.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/a3/a357ac941f0250f016de2212cd729d6cf650feef.jpg","https://suntekstore-img.sfo3.digitaloceanspaces.com/p/e8/e8dd4a46d0fd5832656c28ad20d29e9649547af8.jpg"],"thumbnail_link":null,"link":"https://suntekstore.com/p/DCD-10001199484/","markdown_url":"https://suntekstore.com/p/DCD-10001199484.md","json_url":"https://suntekstore.com/products/DCD-10001199484.json","buy_url":"https://suntekstore.com/buy/DCD-10001199484?qty=1","prop65_warning":null}
