Bridge-Type Pad Eye (U-Bracket), AISI 316 Stainless

The Bridge-Type Pad Eye is essentially a U-bolt shaped fitting that serves as a fixed attachment point on a flat surface. Constructed from marine-grade AISI 316 stainless steel, this pad eye is built to endure the challenging marine environment – it won’t rust or weaken even after years of exposure to saltwater, UV, and weather. It features two flat bases (feet) with holes, which lie flush against the mounting surface when installed, and a curved “bridge” (the U portion) that stands above the surface, forming the actual eye (loop) where you can tie or hook things.

Sizes and Dimensions:
This pad eye type typically comes in multiple sizes. For example, we offer it in Small (34 mm length), Medium (44 mm length), and Large (63 mm length) variants (length refers to the distance between the outer edges of the mounting holes, i.e., the overall length of the “bridge”). The height of the U (how far it stands off the surface) and the diameter of the bar can vary slightly with size. All versions have 2 mounting holes. The holes are countersunk for flathead screws in most cases, allowing a flush finish when installed.

Installation:
You can mount the pad eye using stainless steel screws or bolts. For maximum load capacity, it’s recommended to through-bolt them with backing washers or plates on the opposite side, especially for critical applications like lifting or bearing significant loads. If through-bolting isn’t possible, use strong stainless screws into a solid substrate (e.g., teak, oak, or backing plate embedded) and avoid just thin fiberglass without reinforcement. Seal the screw holes with a marine-grade sealant during installation to prevent any water ingress.

Use Cases:

• On Boats: These pad eyes are extremely handy on decks and in cabins. Small size (34 mm) pad eyes can be used to secure canvas covers, as attachment points for small blocks or fairleads, or as tie-downs for light gear. For instance, install a few around your cockpit to clip on fender lines or to secure an icebox. Medium size (44 mm) ones are great for holding down a dinghy on deck via straps, mounting at the gunwales for clipping carabiners to (like harness tethers or jacklines), or as a fastening point for a bimini top strap. Large size (63 mm) pad eyes provide heavy-duty anchoring – ideal for mooring arrangements, securing large deck cargo, or attaching snatch blocks for sheets on sailboats. They can even be used as lifting points for davits or deck cranes (check load ratings).
• On Docks and Jetties: Use them as cleats/tie points in tight spaces or where traditional cleats aren’t suitable. A row of pad eyes on a dock can guide ropes or secure tarps and safety lines. Their low-profile design reduces trip hazards compared to bulky cleats.
• At Home / Industrial: Because of their sleek look and strength, stainless pad eyes are often used in architecture and home projects. For example, mount one in a garage or workshop wall to create a strong hook point for hanging bikes, tools, or hoisting storage nets. Outdoors, they can be used to anchor sun sails or outdoor string lights (the stainless finish is attractive and blends with modern designs). Rock climbers might even use them (in certified form) as fixed anchors. You can also find them in stage rigging or as part of gym equipment mounts (like attaching resistance bands or swings).

Advantages:

• Low Profile: When not in use, the pad eye lies fairly flat and out of the way, unlike fold-up pad eyes or cleats. This means less chance of tripping or snagging lines when you don’t have anything tied to it.
• High Load Capacity: The U-bridge shape distributes load to two points, and our pad eyes are forged or formed with reinforced sides (especially the larger sizes), giving them excellent strength. They are rated to handle hundreds of kilograms of force (exact SWL varies by size, e.g., small ~0.1 ton, medium ~0.3 ton, large ~0.6 ton when properly mounted).
• Corrosion Resistance: Being AISI 316, they’re suitable even for sailboats that circumnavigate or dock in tropical marinas. No need to worry about rust streaks or weakening. A quick polish now and then keeps them shining.

Usage Tips: If using as lifting or critical load points, always inspect the pad eyes periodically. Check that mounting screws are tight and not corroded. Replace any bolts that show signs of crevice corrosion (rare with good 316 hardware). If attaching heavy moving gear (like a block that could sway), consider using a pad eye with a backing plate or a welded pad eye for extra safety, or ensure the substrate is very solid.

In summary, the bridge-type pad eye is a simple yet indispensable fitting. It’s ideal for any project requiring a permanent, robust lashing point. With easy installation and virtually no maintenance aside from occasional cleaning, it’s a cost-effective way to add functionality and safety to your boat or outdoor setup. Many of our customers keep a few spares, as once you start using them, you’ll constantly find new uses – from lashing down gear to serving as makeshift handles or attachment points for accessories. Upgrade your boat’s hardware with these pad eyes and gain superior versatility and security for all your tie-down needs.
