The parts of a bimini frame
A bimini is a tube frame with a tensioned fabric top. Almost everything that fails is hardware: a jaw slide that works loose, a lost pin or a corroded hinge. Knowing the parts helps you order the right one, and the products above change with stock, so check the tubing size and material.
| Part | Function | What to check |
|---|---|---|
| Jaw slide | Joins two tubes and lets you fold or adjust the bow | Tube diameter and locking screw |
| Eye end | Caps the tube end and gives a fastening point | Eye with enough thickness |
| Deck hinge | Secures the frame to the deck and lets it fold down | Base and pivot angle |
| Rail mount | Attaches the frame to a rail or stanchion | Rail tube diameter |
| Quick-release pin | Removes the top without tools | Pin thickness and length |
| Straps and bracing | Tension the top and stop it flapping | Stainless buckle and quality webbing |
How to measure the tubing and choose the size
Bimini frames are almost always made of 7/8 in (22 mm), 1 in (25 mm) or 1 1/4 in (32 mm) tubing. To get it right:
- Measure the outside diameter with calipers, or wrap a tape around the tube and divide by 3.14.
- Check the wall thickness too: thin-wall tubing needs fittings with a bushing.
- Don't mix metric and imperial: 22 mm tube and a 7/8 in (22.2 mm) fitting match, but 25 mm tube will not fit a 7/8 in fitting.
- With the frame assembled, confirm the tubes overlap enough in the jaw slide: at least twice the diameter.
If you're replacing the whole frame or fabric, first look at the best bimini tops and the guide on how to measure a bimini.
Materials: 316 stainless or aluminum
Bimini hardware takes sun, salt water and constant vibration. So:
- 316 (A4) stainless: the best choice for load-bearing parts such as hinges, pins and fasteners. Type 304 works below deck but rusts outdoors (304 vs 316 stainless).
- Anodized aluminum: light, no iron rust, common in tubing and large fittings. Don't let it touch stainless without an isolator, or you'll get galvanic corrosion.
- Nylon and UV-stabilized engineering plastic: in end caps, bushings and guides. They degrade in sunlight, so replace them when you see cracks.
Warning: use fasteners of the same material as the part and, between aluminum and stainless, a nylon washer or anti-seize paste. This is the cause of most screws seized to the tube.
Installation and deck mounting
- Hold the assembled frame on the deck and mark each base position with the boat at rest and the tubes squared up.
- Check what is under each hole: backing, core or void. Bimini hardware takes strong side loads in wind.
- Fasten with A4 through-bolts, a backing plate and wide washers. Avoid self-tapping screws in unreinforced laminate.
- Seal the holes with butyl or polyurethane (marine sealants) so water can't get into the core.
- Fit the top, tension the straps and check that every point shares the load.
Tip: carry spare base caps and quick-release pins aboard. They're the parts that disappear when the top is folded in a hurry.
Maintenance and common mistakes
Before each season, check fasteners and jaw slides, lubricate moving parts with a marine lubricant and rinse the tubing with fresh water. If you take the top down for winter, store it in its cover (boat covers) and not folded damp.
- Buying a jaw slide without measuring the tube diameter.
- Mixing plain steel fasteners with stainless parts.
- Overtightening the clamp until the tube deforms: lock it without crushing.
- Mounting to unreinforced laminate without a backing plate.
- Leaving the bimini up in a storm: tops aren't designed for strong winds, and the hardware is the first thing to give.

Frequently asked questions
What tube size is a bimini frame?
Usually 7/8 in (22 mm), 1 in (25 mm) or 1 1/4 in (32 mm) tubing. Measure the outside diameter with calipers before buying jaw slides, eye ends or hinges so they fit without slop.
What is a jaw slide?
It is the fitting that joins two tubes of the frame and lets you adjust or fold the bow. It loosens with a locking screw. Choose 316 stainless in the same diameter as your tube.
Stainless or aluminum for bimini hardware?
316 stainless for load-bearing parts such as deck hinges and pins. Anodized aluminum is light and fine for tubing and large fittings, but isolate it from stainless with a nylon washer or anti-seize paste.
How do I mount a bimini to the deck without damaging the laminate?
Use A4 stainless through-bolts with a backing plate and wide washers, and seal every hole with butyl or polyurethane. On a cored laminate, fill the hole with epoxy to protect the core.
