8 Pack Heavy Duty Swivel Top Angle Brackets For Boat Trailers Built Like A Tank Rock Solid Marine Deck Mount Drop Dead Durable Three Millimeter Steel Hardware Not Included

8 Pack Heavy Duty Marine Swivel Brackets for Deck Bunk Use
✔️ 3mm galvanized steel 3.5x1.35x2 inch accepts 3/8 and 1/2 bolts

This marine deck mounting kit gives you eight rugged angle brackets built to hold down boat trailer bunks and cross rails without flexing out. The galvanized zinc finish keeps corrosion at bay when you dunk the trailer in saltwater or wash it off weekly. Each piece features a concave cutout that locks onto cross tubes so your bunk assemblies stay locked in place instead of spinning around when you back down the ramp. The heavy three millimeter gauge thickness stops bending under wave impact or loaded deck shifts. You just drill and bolt them straight into your stringers or transom, skip buying matching fasteners elsewhere, and keep your rig straight across the water.

✅ Eight heavy duty units per box
✅ 3mm corrosion resistant zinc coating
✅ 3.5 x 1.35 x 2 inch compact profile
✅ Rotational locking concave underside
✅ Two inch top hole center alignment

💡 How do marine trailer swivel brackets manage shear loads during rough water transport?
You get reinforced anchor geometry that transfers lateral stress away from sensitive deck seams.
Zinc plated housing coatings neutralize electrolytic reactions between steel fasteners and aluminum hulls.
Bent concave contact surfaces grip cross rails evenly to eliminate rotational torque under pounding waves.
Three millimeter base plates distribute static weight efficiently so cross members never sag during summer outings
