Designed wedges to allow you to adjust the mounting angle. The dock is designed to attach horizontally to the vertical edge of a cart. However, carts vary in manufacturing precision, and some may not be vertical. Added three wedges of different angles so you can adjust the mounting position to your cart. We'll ship to customers who have already purchased the dock 👍すでに購入の方々にもこれらをお送りします！ Boom & Umbrella Dock for Olympia carts is available in our online store 🏬 Check out the online store link in bio 🔥🤗🔥 #olympia #olympiacart #cameragear #cameradepartment #gaffer #filmcrew #filmaker #filmmakersworld #camerasetup #cameradepartment #sounddepartment #sounddesign #sounddesigner #cameracart #backstage #magliner #neewer #manfrotto #inovativ #mottjp /ToT\
