Jack screw mechanism specialized for storage
Spring-loaded tension rods are commonly used for shower curtains, which use the force of the spring to prop against the wall. While spring-loaded tension rods are easy to install and remove, they often have a low load-bearing capacity.
Heian Shindo's storage rods, on the other hand, have a jack screw mechanism. The ends firmly grip onto the wall when you turn the grip. In addition, the thicker pipes prevent deflection even when heavy objects are hung on them. These are designed specifically for storage. Both rod and shelf types are available for a wide range of storage applications.
