The Top End T-5 7000 Series Tennis Chair is made of a lighter weight aluminum and is about two pounds lighter than the previously used aluminum, making the T-5 7000 Series more comparable to titanium frames. This tennis chair also features the Nord-Lock bolt securing system for the axle receivers.

Design Changes
The T-5 7000 Series Tennis Chair features a number of design changes for a sleeker and more secure chair. The head tube utilizes precision components that maximize stiffness, reduce play and improve overall responsiveness of the casters. Also, the frame members sleek and curved design add a sharp look to the camber tubes and anti-tip.

Benefits of 7000 Aluminum
Not only is this type of aluminum lighter than others, but it is also significantly stronger. The additional strength allows for a reduction in the wall thickness of the tubes which reduces weight of the chair. In addition, the rigidity and strength of the 7000 aluminum is further enhanced by Invacare Top End's sophisticated heat treating and powder coating process.

Nord-Lock Bolt Securing System
Axle receivers are locked into the frame with the Nord-Lock bolt securing system. This system minimizes axle play which makes the rear wheels more secure and solid, an important feature in a tennis chair. Nord-Lock bolts have been around since 1982 and they are highly effective in resisting loosening by vibrations and load.

Stronger material allows us to reduce wall thickness of the aluminum tubes, reducing the overall weight. Best of all, the rigidity and strength of a 7000 aluminum frame is further enhanced by Top End’s sophisticated heat treating and powder coating process.

Design: The Top End design team continues to improve the multiple components on the T-5 7000 Series Tennis wheelchair. This system minimizes axle play so that a player’s rear wheels are secure and solid for a confident feel. Lastly, the sleek curved frame members adds a sharp look to the camber tube and swivel anti-tip.

The Designer: Each T-5 7000 Series Tennis Wheelchair is custom built to each individual athlete’s specifications and this process is overseen by Paul Schulte, our Engineering Manager at Top End. Paul has been a member of the USA National Men’s Wheelchair Basketball Team for years playing in multiple Paralympic Games and has held many MVP titles both as a junior and in the men’s division of the NWBA.
