4″ Spring assembly for Gymnastics or cheer floors. This is a good way to figure custom size spring floors, or to add to existing Spring floors. ( 1 spring per square foot is generally used) Example 8′ x 60′ Tumble Strip will be 8 x 60= 480 sq ft so you will need 480 springs.
Note *Our floors now come with the improved Red non skid Rubber bottom caps instead of the hard black plastic caps
Plywood not included with springs
