  • Designed as a drain plug, so it is a simple functional part rather than a multi-purpose accessory.
  • Brass construction is practical for marine use, but it still needs routine inspection and maintenance as part of normal boat care.
  • Intended for standard garboard fittings, so non-standard transom or hull drain setups may not be a fit.
