The Black Nylon Slide Lock with Screw (SKU: 3432B) from Whitecap Marine Products is a compact, durable marine hardware fastener designed for secure positioning in track systems. It consists of a black nylon base with a T-shaped profile that slides into compatible tracks, paired with a stainless steel fillister head screw (slotted for tool use, with a knurled edge for potential hand tightening). The base measures approximately 0.850 inches in width to fit standard marine tracks, while the screw has a 1/4"-20 thread size and a length of 7/8". The nylon material provides corrosion resistance, lightweight strength, and UV stability, making it ideal for harsh marine environments. Overall, the item appears as a small, black rectangular block (about 1 inch long) with protruding lips on the bottom for track engagement, and the screw protrudes upward from the center. It's available in black (3432B) or white (3432W) variants, often sold individually or in pairs, and is commonly used as a top fitting in boat accessory assemblies.

List of Functions

  • Position Locking: Tightens via the screw to secure the lock in place within a track, preventing unwanted sliding or movement of attached components.

  • Corrosion Resistance: Made from nylon and stainless steel to withstand saltwater, moisture, and UV exposure without degrading.
  • Secure Attachment: The screw can fasten or clamp additional elements, such as fabric or hardware, while locking the base.
