We can custom-make adjustable supports of your own design to your desired length. The price is a tentative price per support. Please confirm the following details before purchasing. Suitable for use with cornets, or for trumpets with non-standard designs other than Bach or Yamaha. ・As a guideline, please consider a usable length of approximately 34mm to 65mm based on past experience. Although it is theoretically possible to make longer ones exceeding 65mm, we cannot confirm the "verticality" when installed if we make them without testing on the actual instrument. Errors in precision become more noticeable as the length increases. We will do our best to manufacture them, but we will only accept orders from those who understand this point. ・The design will differ as the length decreases due to the limitations of available parts. As a guideline, please refer to the attached second photo for the relationship between length and design. ・The shortest length will be made to be the usable length minus 2mm to 3mm, considering the installation. ・Please feel free to consult with us if you have any other requests. ●Notes on Ordering ・The price will vary depending on whether we can reuse existing stock or need to make new ones. We have set a tentative price that we believe is the maximum. ・The ordering process is as follows: (1) First, you will inform us of the desired length. (2) We will provide you with the price and delivery time. (3) We will list the completed product exclusively for you. (4) You purchase the product. You are free to cancel the order if you are not satisfied with the finished product at stage (3). ●Things to provide when ordering ・Please provide the desired length in millimeters, rounded down to the nearest whole number (e.g., measurement result is about 47.5mm → please provide 47mm). If you do not have calipers, please refer to the following: ・Method 1: If the part is near the slide, remove the slide and measure the cross-section with a ruler. ・Method 2: Make a dummy of the correct length by gradually shortening the ink tube of a used ballpoint pen, chopsticks, or bamboo skewers with a cutter, and then measure the length of the dummy with a ruler. ●About Delivery Time It may vary depending on the case, but custom-made items may take time. We may need up to a week. Photos 3 and 4 are samples of the product installed on a backpack. The musical instrument itself is not included in the sale.
