Sea-Dog Quarter-Turn Textured Deck Plate w/Internal Collar - Black - 6"

The Sea-Dog Quarter-Turn Textured Deck Plate w/Internal Collar in Black, 6" diameter, is a marine-grade access fitting engineered for vessel deck penetrations, utility compartments, and modular equipment installations where secure, tamper-resistant fastening is critical. Whether securing hatches on patrol boats, military vessels, or tactical watercraft, this quarter-turn deck plate eliminates the need for multiple tools and provides positive locking without over-tightening risk—a proven standard in naval operations and law enforcement maritime units.

Constructed from UV-stabilized ABS polymer, the Sea-Dog deck plate resists saltwater corrosion, UV degradation, and thermal cycling—essential for prolonged outdoor and marine environments. The innovative quarter-turn locking system prevents cross-threading, jamming, and accidental loosening caused by vibration or personnel error, while the internal collar provides rigid structural support and alignment under load. The textured surface improves grip traction in wet conditions, reducing slip hazards during equipment access or emergency egress scenarios typical in military and law enforcement field deployments.

This deck plate is ideal for boat builders, naval technicians, and tactical operations teams requiring reliable deck hardware that withstands saltwater exposure, repeated cycles, and high-use environments. The 6" form factor suits standard through-deck applications on mid-sized vessels and modular tactical platforms. Installation is straightforward—mount through existing 6" apertures using the internal collar as a positioning guide, then secure from below with the quarter-turn fastener. Compatible with marine-grade gaskets and sealants, this component delivers professional-grade durability at a field-proven specification.
