Ultimate TS99B Tall Speaker/Light Stand With TeleLock The TeleLock™ Series speaker stands from Ultimate Support are extraordinarily strong yet lightweight due to its over-sized heavy wall aluminum tubing. They're everything you'd expect from an Ultimate Support speaker stand - they're strong, sturdy, lightweight, 100% field serviceable, and easy to set up and take down. However, the TeleLock collar gives the user the ability to safely raise or lower the stand WHILE a speaker is on it thanks to the Auto-lock technology that securely grips the telescoping tube in place as you set its height.TS-99B Product Breakdown: Patented TeleLock Collar Extra Height Patented Tripod Design Over-sized Heavy Wall Aluminum Tubing 100% Field Serviceable PartsPatented TeleLock Collar The TS-99B is one of the easiest speaker stands to use thanks to its patented TeleLock collar. Set the TeleLock collar to either the "Raise" or "Lower" setting and the Auto-lock technology provides just the right amount of resistance to allow you to raise or lower the speaker while locking the tube in place as you go. It's like having tour support built into your speaker stand!Extra Height The TS-90B is plenty tall enough for most normal situations. However, when you need to get your speaker, lighting tree, light truss, or whatever, up a little higher, the TS-99B is the perfect stand for you! The TS-99B adds about 26 inches of additional height and has a maximum height of 9' 2"!Patented Tripod DesignThe TS-99B's offset tripod base design provides more support than typical "off-the-shelf" speaker stands. The design makes for very tight internal fittings, doing away with unnecessary sloppy leg problems, and includes a super strong die-cast metal collar that prevents over-tightening and breakage issues associated with all plastic designs.Over-sized Heavy Wall Aluminum Tubing The entire stand (legs, mast, and telescoping tube) uses oversized, heavy-walled aluminum tubing for durability, functionality, and weight savings. The TS-99B will not rust or corrode (thanks to its architectural anodized finish), is very smooth to operate, and is extraordinarily strong yet lightweight.100% Field Serviceable Parts From the foot caps on the bottom of the tripod legs all the way up to the speaker adapter at the top of the stand, the TS-99 is serviceable by parts as needed over its very long lifespan. In the unlikely event that something does break on the TS-99, simply replace with an affordable part instead of throwing the entire stand away and buying a whole new one!In Depth Product Specs: Height: 5'2"- 9'2" (1575 mm - 2794 mm) Weight: 9.8 lbs.
