Securing a marine or RV battery box requires the correct strap length and anchor hardware. Sea-Dog's 415082-1 heavy-duty hold-down kit uses a 48-inch strap, stainless buckle and chrome-plated brass brackets. The 415092-1 uses a shorter 38-inch strap and nylon buckle with a different bracket design. Both are complete strap-and-bracket kits.

Match the anchor arrangement: The 48-inch 415082-1 includes a stainless buckle and chrome-brass brackets. The 38-inch 415092-1 includes an injection-molded nylon buckle and two brackets. The manufacturer's A/B/C/D drawing measurements refer to specific hardware features, not automatically the battery-box interior dimensions.

Kit contents: Sea-Dog lists four #8 flat-head fasteners with each of these two strap kits. The heavy-duty version has two chrome-plated brass brackets and a stainless buckle. The shorter version has two brackets and a molded nylon buckle. Confirm the supplied kit against the individual product listing.

For original specifications and installation guidance, see the manufacturer's references: Sea-Dog heavy-duty strap, Sea-Dog standard strap.

What to check before ordering

  1. Measure the distance around the battery box and the existing anchor route; leave enough strap length for a secure buckle connection.
  2. Identify the buckle type and the original bracket attachment holes before choosing a replacement.
  3. Check the 48-inch versus 38-inch listed strap lengths and the manufacturer's labelled hardware dimensions.
  4. Install the supplied brackets and fasteners into a structurally suitable mounting surface using the manufacturer's instructions.
  5. Confirm the battery or box is restrained against movement, and inspect for worn straps, corrosion and interference with electrical terminals.
