Detailed FAQ Section

How strong is the Weld Mount AT-5 Mount Large Black 30 Pack for Boats & Marine Engines?

This mount is rated to hold up to 50 lbs in tension when bonded with the recommended AT-8040 adhesive. It can withstand heavy loads, vibrations, and temperature fluctuations common in engine rooms and marine decks. Thanks to its UV-stabilized nylon construction, it resists sun exposure and chemical damage, maintaining performance over years of use.

The strength comes from both the mount’s design and the adhesive’s advanced bonding technology. For best results, ensure surface preparation is thorough and follow all adhesive curing instructions.

Can I use this on vertical or overhead surfaces?

Yes, the Weld Mount AT-5 Mount Large Black 30 Pack is engineered specifically for hard-to-reach and vertical surfaces. When used with Weld Mount’s AT-8040 No-Slide Multi Bonder, you get excellent performance even when the mount is placed on ceilings or bulkheads.

Ensure that during curing, the mount remains undisturbed. AT-8040’s thixotropic gel formula prevents dripping, allowing solid adhesion even in non-horizontal orientations. Many marine electricians use it for cable runs in overhead conduits, T-tops, or behind wall panels.

Is this mount UV and saltwater resistant?

Absolutely. The nylon used in the Weld Mount AT-5 is UV-stabilized, making it ideal for exposed deck installations. It is also resistant to salt spray, making it suitable for saltwater and offshore vessels. It meets marine standards for corrosion resistance and will not become brittle or degrade over time when exposed to the elements.

This makes it a preferred solution for both interior and exterior marine rigging tasks, particularly where metallic fasteners would corrode.

What size cable ties fit into the Weld Mount AT-5 Mount?

The AT-5 mount is compatible with standard 50-lb tensile strength cable ties with widths of 0.19″ (4.8mm). It is engineered for mid- to large-diameter cable management, perfect for electrical harnesses, navigation wiring, and hydraulic hose restraints.

You can use marine-rated black UV cable ties or color-coded options based on your wire configuration needs. Make sure not to overtighten the cable tie, which could damage cables or stress the mount.

Can I remove or reposition the mount once installed?

While the Weld Mount AT-5 is semi-permanent, it can be removed by applying heat (around 200°F) using a heat gun to soften the adhesive bond. Once softened, you can gently pry the mount off using a plastic scraper. Any residual adhesive can be removed using a marine-grade solvent or adhesive remover.

Keep in mind that repositioning is not recommended once cured, so be sure of your placement during the initial install.

Conclusion

If you’re looking for a non-invasive, secure, and marine-grade solution for cable and hose management, the Weld Mount AT-5 Mount Large Black 30 Pack for Boats & Marine Engines is your answer. Trusted by pros and engineered for performance, these mounts offer a balance of strength, convenience, and durability that makes them a superior choice for any vessel.
