End, Bottom, and other caps

Caps are a convenient way to protect shrinkwrap from tearing when wrapping over an angled surface.  End caps and Corner caps provide a smooth transition for your shrink wrap to go around sharp changes in the angle while avoiding rips and tears.  End caps are placed on the upper end of a vertical 2x4 which acts as a support post for your shrink wrap structure.  Bottom caps are placed on the lower end of a vertical 2x4 to protect the floor surface from scratches while helping to keep the vertical support in place.  Corner caps provide a quick and easy alternative to padding corners before applying your wrap.  Typically, End and Bottom caps are used in support structures on the decks of boats.  Corner caps are used when wrapping crates and other square objects with sharp corners.
