Built as one complete unit to aid in uplift resistance, this
Steel Shore will not come apart.  We've designed the wingnut
assembly to house tiny bearings that allow for significantly less
friction and easier turning under load.  The 6 x 6 inch top plate is
attached with a clevis pin and interchangeable with different sizes.

Choose from any of the sizes above and we will
customize your Steel Shore so it will not come apart. 
The chart below illustrates several options to choose from.

In the product animation to the left, you will notice the needle bearings inside the wingnut.  Thes bearings greatly reduce the amount of friction when the handle is turned to adjust the height under load.
