Adjustable spring design provides a firm hold on outdoor camping surfaces such as wooden boardwalks and anticorrosion boards. Constructed from steel and aluminum alloys, offering good crush resistance and wear resistance to maintain stability in complex environments. Simple and practical for boardwalks and deck camping: insert the slot in the wood board and rotate to lock as a fulcrum to fix the tent. Fishboneshaped design improves stability, helping prevent tent stakes from loosening or rotating when the tent moves or sways. Compatibility and use: designed to work with wooden decks, boardwalks, docks, and similar raised wooden platforms; fits into a slot in a wooden board for secure anchoring. How to use: place the peg in a wood deck slot, insert fully, then rotate to engage as a fulcrum to stabilize the tent. Use scenarios: Camping on seaside or marina boardwalks where ground is unsuitable for traditional stakes, providing secure tent anchoring on wooden surfaces. Setting up a temporary campsite on wooden boardwalks during outdoor events or festivals, improving stability in windy conditions. Glamping or camping on anticorrosion treated wood surfaces at coastal locations, where durability and reliable support are required.
