摘要:
Ladder modules are provided in manageable length sections. The first section is secured at the top with a multi-hole horizontal mounting bar that is secured by a ratchet strap with hooks. The bottom of the first section rests firmly on the ground with a cleat at the bottom to secure the ladder section and prevent shifting. The second section contains a ball on the bottom of the structure that is mounted onto the first section by placing the ball into the receiving end of the first section, which allows the second section to pivot 360 degrees and lean and tilt fore and aft. This section is also secured to the tree with a ratchet strap and hooks, and is safe to climb to the next section after tightening the ratchet strap. Additional sections can be added in the same manner as the second section to pivot and level as needed.
