COLLARCONE HOLE SAVERS are often referred to as Collar Protectors or Drill Hole Cones. They are designed to protect the integrity of a hole and come in a range of sizes. The MTi Group COLLARCONE HOLE SAVER is injection moulded instead of rotationally moulded, which means it is up to 20% lighter than other products while being higher quality. The MTi Group COLLARCONE HOLE SAVER features downline clips moulded into the cone to allow for downline retention and is designed to easily stack without sticking together due to antilock tabs. Larger sizes (230 mm +) feature an open bottom for loading through the cone, while smaller sizes are closed allowing for long term hole retention and resistance from the elements.
