This 50 in. backboard is constructed with a shatter proof Makrolon®polycarbonate playing surface for a professional glass look and excellent rebounding performance. The Slam-It® Rim is designed with double compression springs for spring-back action. Use our Lifetime Universal Mounting Kit to mount backboard and rim to a wall, roof, or existing 3.5 inch pole (mounting kit sold separately). If you would like the option of adjusting the height of the backboard, use our Quick Adjust® Conversion Kit (sold separately). If you are replacing an existing backboard, please call an online sales representative to verify compatability. Lifetime basketball backboard combos are built with powder-coated steel to resist rusting and cracking. The Makrolon® backboard is many times stronger than acrylic, making it virtually shatter proof. Graphics are UV-protected to resist fading. Made in the USA from US and imported parts. Covered by a 5 yr. limited factory warranty in US and Canada. Includes all-weather net.
