Castings for the backyard beam

ABUSA Swing Hardware, Cast Iron, and Wool

We cast our swing hangers in one piece from an aluminum alloy and fit each with a sealed bearing. The swing turns on rolling elements against your timber beam, silent in the yard through spring rain and summer sun.

The four workshop lines

We run our foundry around four plain objects. Each has its own shelf below, with parts pictured alongside the lumber they fit.

Matching the casting to your timber

A porch header, a garage joist, a standalone yard beam, or an A frame you bolt together on the lawn all take different fixings. We cast our pockets for dry lumber, ready for the drill bit once your wood has dried out from the yard.

A porch header

A 4x6 header or a doubled 2x8. The hanger sits on the underside on lag screws, or on a through bolt where you can reach both faces of the wood.

A garage or ceiling joist

Look for 2x6 or 2x8 overhead. Where the joist sits away from the spot you want, a short 4x4 laid across several joists carries the hanger instead.

A standalone yard beam

A 4x6 lying across 4x4 legs. Twelve feet of top beam holds three swings without a post in the middle; ten feet holds two.

An A frame you bolt together

Corner castings sleeve the legs onto the beam. We cut the pockets for dry dressed lumber, so the wood slides in rather than getting driven.

Pick what you plan to drill into and we point you to the right shelf of hangers, brackets, or kits.

Building the frame from lumber

Corner castings sleeve 4x4 legs onto a 4x6 beam, so the only cuts you make are square ones. The kit version arrives with the seats and chain already matched to the hangers.

What gets asked about most

This row is ordered by how many ratings each listing carries, so the wool insoles sit above the swing hardware. That is a count of feet, not a verdict on the castings.

Over 5,000 lbPrinted on the hanger listing

That number describes a casting pulled on a test rig, one hanger at a time. It says nothing about the wood you are drilling into, the age of that wood, or the screw you drive through it. The weakest part of a backyard swing is almost never the metal. We keep one page on where figures like this come from, what the CPSC handbook actually covers and what it leaves out: what the numbers mean.

Layouts from park guides and plan books

Park guidelines for public playgrounds and the build sheets from wooden swing makers suggest different gaps between ropes. We set those published layouts side by side so you can compare the original plans before drilling your header.

Four published layouts side by side. We copied the figures rather than averaging them, because they disagree.

What comes in the carton

We pack the hardware and the fasteners we cast for, while you supply the lumber, the tools, and the swing seat.

Inside our carton

  • Cast aluminum alloy hangers with internal sealed bearings
  • A frame corner castings with through bolt openings
  • Lag screws and washers matched to the hanger base holes
  • A paper drilling template marked for your timber face

Exactly what ships depends on the listing you open.

What you supply

  • Dry dressed lumber for the top beam and legs
  • A swing seat with its top attachment links
  • A wood drill bit and a matching hand wrench
  • Ground anchors to pin the frame feet into the dirt

None of this is in our carton, and none of it is priced here.

Notes from the drill press

We wrote down the answers to the questions folks ask us before starting a backyard build.

All 10 bench notes

Looking over the hardware in spring

Take a walk out to the frame before anyone sits on the swing. Check the bolt heads against the wood, look where water rests in timber checks, and wipe the chain clean. A few minutes with a wrench on dry wood keeps the joint firm for the sunny months ahead.

  • Put a wrench on every lag head and nut before anyone sits down.
  • Look at the wood around each hole for a split running with the grain.
  • Check the gap on the S hooks and close the ones that have opened.
  • Wipe the chain dry and find the link worn thin where it meets the hanger.
  • Push the frame sideways and watch the feet for movement in the dirt.
  • Clear the ground front and back, twice the height of the beam.

Wool liners and a cast iron press

We pour iron and cut wool because we like honest tools. Our tortilla press is heavy gray iron that flattens masa between cut sheets of plastic. Our sheepskin insoles are soft wool skins to line your boots for winter warmth, plain and unshaped.

Sheepskin insoles

Sheepskin cut to a footbed shape, wool side up. Trim the toe with scissors against your old insole and drop it in.

Tortilla press

Gray iron with a lever arm, eight inches across. Masa goes between two cut sheets of plastic and comes out flat.

Why we cast without welds

A casting poured in one piece has no soldered seams to part under hard use. We seat the bearing inside the shell to keep dirt out and silence iron squeaks. If a part does not suit your timber, we would rather help you find that out before you drill.

Choosing hardware for your overhead beam

Your overhead timber determines which hanger base you need. A broad porch header takes a flat plate with lag screws, while an A frame uses corner sleeves to join the legs. Getting the timber dry before assembly prevents gaps around the bolt shanks later.

If you are hanging a single seat from a porch joist, start with a pair of quiet bearing hangers. If you are building a yard set from lumber, begin with corner brackets, build the frame flat on the grass, and lift it into place once tightened.

The lineWhen it is the right shelfWhere to start on it
Swing hangersThere is already wood overhead and it can take a screwA pair of sealed bearing hangers, plus chain if the old set is worn
Swing set bracketsThe frame does not exist yet and you are buying lumberCorner castings, or the kit that arrives with seats and chain
Sheepskin insolesBoots that let the cold through the soleYour usual shoe size, one pair, trimmed to the footbed with scissors
Tortilla pressMasa on the counter and no patience for a rolling pinThe eight inch adjustable press and a cut sheet of plastic

Where to begin

Start with the wood overhead. Check whether you have an existing joist or need to build an A frame on the lawn, then select the hangers or bracket kits cast for that lumber shape.

If you are replacing squeaky iron hooks on an older wooden set, pick a pair of sealed bearing hangers and use our paper guide to match the holes in your beam.

What they wrote afterwards

Six of them, left on the listings at our retail partner and copied over as they were typed, misspellings and all. One says a bracket cracked when it was hammered onto a snug 4x6. It stays in, because that is the thing that goes wrong most often with these, and a page of clean fives would tell you nothing.

These are sturdier than I anticipated. They appear well-made and the little stickers for marking the holes, though a trivial thing, are pretty helpful.

Agent Dave5 of 5, August 21, 2026, on Green swing hangers, 2 pack

Bought one and the 4x6 was a little snug, so when I forced the bracket onto the 4x6 with a hammer it cracked the bracket. Bought a new set and shaved the 4x6 down a little, it went on. After assembled I swung on it and no issues. Built the swing for my grandchildren and they love it. Replaced an old swing we had for years. I would buy again.

Gary Bailey5 of 5, May 11, 2026, on Green A frame brackets with four hangers

I bought these to put in a pair of shearling slippers whose insoles were worn out and coming loose. Great choice! These are substantial replacements, super-plush and comfortable, and they fit perfectly inside. No sliding around, well-cushioned below, easy to insert, and they feel like they'll stand up to a lot of use.

These brackets are very sturdy and heavy duty. They feel well made, and I like that all the necessary hardware is included, which makes installation easier. They worked well for putting together a solid A-frame swing set. They’re a good quality set of brackets, a fair value, and seem to be made of durable materials. They fit snugly and have been a convenient option for my DIY swing set.

These chains do what they’re supposed to and feel solid enough for general/residential use. Installation is straightforward. Time will tell how they hold up, but initial impressions are good. The yellow sections are a nice tactile buffer, as they provide a barrier between cold steel and hands - also reduces the chance of skin being pinched between twisting metal links.

Scott J. Machalk5 of 5, April 6, 2026, on 66 inch swing chains with quick connect hooks

Sturdy swing set and brackets. My grandsons love it. Their dad, grandad and uncle put it together and had them swinging and enjoying it in no time. They are rambunctious so I needed a swing set that will hold up. I’ve used the swing myself to check it out. Great product.

Sandra R.5 of 5, July 21, 2026, on Green A frame swing set kit with two seats

A listing carries one pool of reviews for every colour and pack size under it, so the finish on the page we link to need not be the one the writer bought.
