Especially strong and easy to grip thanks to its larger diameter tubing, the Folding Devon Deluxe Toilet Support Rail is spring loaded for easy folding.The support arm can be raised and will remain in the vertical position with the locking mechanism securing it in place. The arm is then easily lifted to release from the lock, which activates the spring mechanism which in turn supports the weight of the rail as it lowers smoothly to the horizontal position.Maximum load weight is not the weight of the user but is the amount of downward force they are likely to exert when using this product.To install this item we recommend you use a qualified professional.
