Featuring adjustable L-brackets and a ball-end design, it allows flexible positioning and fits perfectly on angled boat hatches. Key Notes for Marine Use: 1.Corrosion Protection: Constructed with carbon steel and pre-treated with anti-rust coating, the struts may still rust when exposed to saltwater for long periods. For permanent marine applications, an additional protective coating is recommended, or you can choose our stainless steel version instead. 2.Bracket Maintenance: The standard L-brackets work well under normal use. However, saltwater corrosion and hull vibration at sea can shorten their service life, so regular inspection and maintenance are advised. 3.Mounting Screws: Mounting screws are sold separately. Please select the appropriate screws based on your boat hatch material (wood/fiberglass/aluminum). Is it weather resistant This HUOPO gas strut is made of carbon steel with a QPQ surface treatment, delivering reliable anti-rust and corrosion resistance performance. For daily use, avoid prolonged exposure to humid environments; if used outdoors, proper shielding and protection are recommended to effectively extend the service life of the gas strut. Dose it come with mounting hardware? Included in the package: 2 gas struts, 4 adjustable L-shaped mounting brackets, 4 nuts and 1 installation manual. Mounting screws are not included and need to be purchased separately based on your actual mounting surface material (e.g., camper bed). Note: The included brackets may bend if the weight limit is exceeded. For heavy-duty installation applications, please ensure the bracket load capacity matches your requirements. If you have any questions, feel free to contact HUOPO customer service for assistance. What screws do I need? The specific screw size to use depends on your actual installation application: For wooden frames such as camper beds, you can choose 3/8" lag bolts (equivalent to M10 metric size), or alternatively 5/16" machine screws with washers (equivalent to M8 metric size) — a length of 1.5-2 inches is recommended for both. For metal mounting surfaces, 5/16" bolts with nuts (equivalent to M8 metric size) are required, and washers must be used to distribute the load. Based on feedback from most customers, 3/8" lag bolts are the best match for this gas strut. For heavy-duty installation applications, we recommend upgrading to steel bolts with washers to prevent bracket bending. Does it come with installation instructions? Every HUOPO gas strut comes with a detailed installation manual, and most customers report the installation is extremely easy. You only need to prepare the following basic tools: 1.Wrench or screwdriver: For tightening bolts and screws 2.Measuring tape: To accurately mark the mounting positions 3.Marker pen: To assist with precise positioning of mounting points 4.Level: To ensure the mounting surface is flat 5.Electric drill: For drilling additional holes if needed The entire installation process is simple and straightforward.
