Short answer: Bed rail brackets join the side rails of a wood bed to the headboard and footboard posts so the bed can be taken apart and moved. The three common styles are hook plates (which need a mortise cut into the post), no-mortise corner brackets (which screw to the rail and hang on lag bolts in the post), and corner brackets with a lip (which drop into a saw kerf in the rail). For most builders, a heavy duty no-mortise corner bracket is the easiest to install and the stiffest in use. Slat brackets then carry the slats that hold up the mattress. Bear Hollow Supply designs and casts its own bed brackets in Holmes County, Ohio, and they are the hardware most of the Amish furniture shops in our area use.
This guide explains the bracket types, how to pick between them, and how to install our no-mortise corner bed brackets and slat brackets. Browse the full bed hardware collection here.
Why bed hardware matters
A bed is a big piece of furniture that has to come apart to get through a door, then go back together tight with no wobble. The joint between the side rail and the post takes all of that abuse: every time someone sits on the edge, rolls over, or a kid jumps on the mattress, the rail tries to rack against the post. Cheap stamped steel hardware flexes, loosens, and squeaks. A good bracket is stiff enough that the bed feels like one piece and still knocks apart in a minute when you move.
Types of bed rail brackets
Hook plates (mortise style bed rail fasteners)
The traditional method. A steel plate with hooks mounts in a mortise cut into the end of the rail, and a matching plate with slots mounts in a mortise in the post. The rail hooks drop into the post slots. They work well and sit flush, but you have to cut accurate mortises in both the rail and the post, which takes a router jig or chisel work and adds time to every bed. They also depend on the fit of the mortise; a sloppy mortise means a loose bed.
No-mortise corner brackets
A one piece cast bracket that screws to the inside face of the rail at the end. The bracket has keyhole slots that hang on lag bolts driven into the post. No mortise in the rail, no mortise in the post. You pre-drill, drive screws and lags, and hang the rail. This is the fastest style to install and, with a heavy casting, the stiffest. Our No-Mortise Corner Bed Bracket is this type. Each set of four includes the lag bolts and screws.
Corner brackets with a lip
Similar to the no-mortise style, but the bracket has a lip that sets into a saw kerf cut across the inside of the rail. The lip carries the downward load on the rail itself instead of putting it all on the screws, which some builders prefer on heavy beds. It takes one saw cut per rail end. Our Corner Bed Bracket with Lip and Sleigh Bed Corner Bracket are this type.
Corner brackets without a lip
The same bracket body with no lip, so no saw cut. Our Corner Bed Bracket No Lip is sized for twin beds and for beds with under bed drawers, where the drawer boxes leave no room for a kerf and a lip.
Sleigh bed brackets
Sleigh beds have curved headboards and footboards, and the rail often meets the post at an angle or on a wider face. A sleigh bed bracket is shaped for that geometry. Our Sleigh Bed Corner Bracket is a lipped style sized at 4-1/2 inches wide by 3-3/4 inches long.
Slat brackets
Once the rails are hung, something has to hold the slats that support the box spring or mattress. Slat brackets screw to the inside of the rail and the slat drops into them. Ours have a cast-in locating pin; you drill a hole in each slat end and the slat sits on the pin so it cannot slide. Our heavy duty slat brackets are made for 3 inch wide slats and come in sets of eight with screws. The dovetail slat brackets are the same idea for slats with a dovetail cut on the end.
Which bracket should you use?
| Situation | Bracket |
|---|---|
| Most full, queen, and king beds; fastest install | No-Mortise Corner Bracket |
| Heavy beds where you want the rail to bear on a lip, and you have a table saw | Corner Bracket with Lip |
| Twin beds, bunk beds, captain's beds with drawers | Corner Bracket No Lip |
| Sleigh beds | Sleigh Bed Corner Bracket |
| Holding slats on any of the above | Slat Brackets or Dovetail Slat Brackets |
| Complete bed | Corner Bracket and Slat Bracket Bundle |
| Production shops | 25 set packs of corner brackets and slat brackets |
A bed needs four corner brackets, one at each end of each side rail. Slat count depends on the bed: a queen with a box spring typically uses three to four slats, a platform bed with no box spring needs many more. Each slat needs two slat brackets, one per end.
How to install no-mortise corner bed brackets
You need a drill, a bit for the screw pilot holes, a bit for the lag pilot holes, a driver for the screws, and a socket or wrench for the lags. Our product page has an installation video, and the steps are:
- Position the bracket on the rail. Set the bracket on the inside face of the side rail at the end, with the bottom lip of the bracket tight against the bottom edge of the rail. That lip registers the bracket so every rail ends up at the same height.
- Mark and pre-drill the rail. Mark the screw holes through the bracket, remove it, and drill pilot holes. Pilot holes matter in hardwood; without them the screws can split the rail or strip.
- Screw the bracket to the rail. Drive the included screws until the bracket is tight. Repeat at the other end of the rail and on the second rail.
- Mark the post. Hold the rail in position against the post at the height you want the rail to sit, and mark the lag bolt locations through the keyhole slots. Make sure both posts are marked at the same height, or the bed will sit crooked.
- Pre-drill and drive the lags. Drill pilot holes for the lag bolts in the post and drive the lags, leaving the heads proud enough to drop into the keyhole slots. The right standoff is the one that lets the bracket hang on the lag shank snugly without the head binding.
- Hang the rail and tighten. Lift the rail, drop the keyhole slots over the lag heads, and let the rail settle down onto the shanks. If there is any play, snug the lags a quarter turn until the rail hangs tight.
- Install the slat brackets. Space them evenly along the inside of both rails at matching positions, screw them on, drill the pin holes in the slat ends, and drop the slats in.
Install tip: do the lag layout on both posts with a story stick or a spacer block so the height is identical. Most crooked beds come from a lag that is 1/4 inch off on one side.
Installing lipped corner brackets
The sequence is the same, with one extra step. Before mounting the bracket, cut a kerf across the inside face of the rail where the bracket lip will sit. The kerf width and depth match the lip on the bracket. The lip drops into the kerf, the bracket is screwed on, and from there the install is identical. The Corner Bracket with Lip and No Lip versions share the same 4-1/2 inch by 2 inch by 1-3/8 inch body.
About our bed brackets
Our founder designed these brackets more than twenty years ago for the furniture shops around us in Holmes County, Ohio, and we have been making them since the mid 1990s. They are cast, not stamped or bent, which is why they are heavier than anything you will find at a big box store and why they do not flex. The hardware distributors that supply the Amish furniture industry have carried them for years, and we sell them direct in retail kits with the fasteners included. Every bracket carries a lifetime limited warranty against defects.
Frequently asked questions
What is a no-mortise bed bracket?
A corner bracket that mounts to the surface of the bed rail and hangs on lag bolts in the post, so you do not have to cut a mortise in either piece. You pre-drill, screw the bracket to the rail, drive lags into the post, and hang the rail.
How many bed rail brackets do I need?
Four corner brackets per bed, one at each end of each side rail. Slat brackets are two per slat. A set of eight slat brackets covers four slats.
Do bed rail brackets come with screws and bolts?
Our retail sets do. The No-Mortise Corner Bed Bracket set includes four brackets, lag bolts for the posts, and screws for the rails. Slat bracket sets include screws. Wholesale case quantities are available without hardware for shops that stock their own fasteners.
What size slats do the slat brackets fit?
Our heavy duty slat brackets are made for 3 inch wide slats. Each bracket has a cast-in pin; drill a matching hole in the end of the slat so it locks in place and cannot slide.
Can I use these brackets on a bunk bed or a bed with drawers?
Yes. The Corner Bed Bracket No Lip is made for twin beds and beds with under bed drawers, since it needs no saw kerf and keeps the rail face clear.
What is the difference between a bracket with a lip and without?
The lipped bracket has a tab that sits in a saw kerf cut into the rail, so the rail bears on the lip as well as the screws. The no lip version mounts with screws only and needs no kerf. Both use the same bracket body.
Will the bed wobble or squeak with these brackets?
Not if the lags are snug. Cast brackets do not flex the way stamped steel does, and the keyhole hang pulls the rail tight to the post. If a bed develops play over time, a quarter turn on the lags takes it out.
What is the warranty on Bear Hollow bed brackets?
A lifetime limited warranty against any defect in the product.
