Okay, for anyone who needs to mark lines on courts, fields, or parking lots - this line marking applicator is seriously a game-changer! Made from durable stainless steel with rubber wheels, this thing is built to last through years of use. The best part? It uses tape instead of paint, so no messy cleanup or permanent marks if you make a mistake. The spacing between lines is adjustable from 1.18 to 5.9 inches to accommodate different tape widths and standard requirements. It handles tapes up to 5.5 inches wide with 1.5-inch or 3-inch inner diameters. But here's the really cool feature: it can mark perfect circles with radii up to 7 meters (about 23 feet) using the circle attachment! Just loosen the hinge device for circles or tighten it for straight lines. The wide wheel base and soft rubber wheels apply even pressure for excellent tape adhesion without bleed-through. Perfect for basketball courts, tennis courts, playgrounds, parking lots, warehouses, or any area needing temporary or permanent markings. So much easier than kneeling down and measuring everything by hand - you can mark lines quickly from a standing position. The quality construction ensures your lines stay straight and your circles stay round season after season. Seriously, if you're responsible for maintaining any kind of court or field, this tool will save you so much time and frustration!
