Steel end walls are a good alternative to wood, offering advantages that include longevity and resistance to
moisture and pest damage. This kit includes steel beams and hardware to configure your end walls to your
specific needs. Please refer to your Bobcat Tunnel Manual for guidance on designing your end walls.

ASSEMBLY INSTRUCTIONS
1. Start by digging two holes in the approximate location of the vertical
beams that will sit on either side of your door.
2. Attach an end wall bracket to the end of two 12' 4" steel beams using
the 1" Tek screws (see figure 1).
3. Use the end wall brackets to loosely attach these two vertical beams
to the end wall bows, using the top brace band you previously
installed, 1½" carriage bolts, and hex nuts (see figure 1). These will
be the sides of your door frame, so space them just wider than the
door you will be installing. Once the studs are plumb, tighten the
bolts, and pack soil around the bottoms to hold them in place.
4. Cut a length of 1½" steel beam for the top of the door frame using a
circular or reciprocating saw with a metal cutting blade.
5. Install the top of the door frame between the two vertical beams
using 1½" angle brackets on both the top and the bottom of the
horizontal beam and 1" Tek screws (see figure 2).
Note: Be sure the top door frame is level and set at a height so the
bottom of the door rests about 1" above ground level.
