Door Stopper and Flush Bolt Order: 1 per Leaf, 2 per Pair
Order one door stopper per leaf and two flush bolts per pair of doors, top and bottom on the inactive leaf, plus one floor socket for the bottom bolt. Choose a wall stop such as DS01 where a solid wall is in reach and a floor stop such as DS05 where it is not.

Quantities per door
Take these off the door schedule by leaf, not by opening. A pair is two leaves, so it needs two stops even though it has one set of flush bolts.
| Opening | Door stops | Flush bolts | Floor sockets | Coordinators |
|---|---|---|---|---|
| Single door | 1 | 0 | 0 | 0 |
| Single door with a closer | 1 | 0 | 0 | 0 |
| Pair, inactive leaf bolted | 2 | 2 | 1 | 0 |
| Pair with a rebate or astragal, both leaves self-closing | 2 | 2 if the door allows them | 1 | 1 |
Example: 40 single doors and 10 pairs
That schedule has 60 leaves, so it takes 60 door stops. The 10 pairs take 20 flush bolts and 10 floor sockets. Split the 60 stops by wall and floor before you order, because the rooms decide it, and split any tall pairs out of the flush bolt count, because they need a longer bolt.
Which door stopper for which door
| Model | Type | Fixing | Listed | Suits |
|---|---|---|---|---|
| DS01 | Wall stop, white buffer | Wall or baseboard | Stainless steel, 96mm projection, 34mm base | Rooms with a solid wall behind the door |
| DS022 | Wall stop, black buffer | Wall or baseboard | Zinc alloy, five finishes | The same, where you want a tapered body |
| DS02 | Wall stop with coat hook | Wall or baseboard | Stainless steel | Bedrooms and washrooms, where a hook is useful |
| DS05 | Floor stop, half dome | Floor | Stainless steel, 44mm diameter x 24mm | Doors with no wall within reach |
| DS010 | Floor stop, half dome | Floor | Zinc alloy, 42mm diameter | The same, in brass and nickel finishes |
| DS09 | Floor stop, side buffer | Floor, two screw holes | Zinc alloy, 42 x 35mm | Floors where the buffer should face the door |
| DS013 | Kick-down door holder | Door face, low on the door | Zinc alloy | Doors held open by hand, such as a store room |
Wall stop or floor stop
- Measure first: a wall stop has to touch the door before the lever or pull reaches the wall.
- DS01 projects 96mm, so compare that with how far your handle stands off the door.
- A wall stop needs a solid wall or baseboard behind it, not a hollow panel.
- A floor stop goes on the door's swing path toward the lock side, not near the hinges.
- A stop close to the hinges works against the door's leverage and loosens the hinges.
- Keep floor stops out of the walking line, because they are a trip hazard, most of all in care buildings.
- Do not use DS013 on a fire door or on a door with a closer.
Which flush bolt for which pair
A flush bolt sits recessed in the meeting stile of the inactive leaf, so it only shows when the active leaf is open. The top bolt goes up into the frame head and the bottom bolt goes down into the floor. Never fit one on the hinge edge, and a single door does not need one.
| Model | Operation | Listed | Suits |
|---|---|---|---|
| FB001 | Thumb slide in a recess | 205mm long, 230mm with the bolt thrown. Face 19mm, 32mm deep. Lengths 8, 10, 12 and 24 in | Pairs of ordinary height, with the slide within reach |
| FB017 | Lever in a recess | 22mm wide. Lengths 8, 10, 12 and 24 in | Wooden gates and windows, as listed |
| FB013 | Lever in a recess | Stainless steel, nine finishes. Size confirmed against your drawing | Pairs that need a stainless body |
| FB014, FB015 | Lever in a recess | Stainless steel. Size confirmed against your drawing | Pairs in a brass tone, as photographed |
| FB016 | Lever with extension rod, as photographed | 7 in body, 24mm wide | Tall pairs, where the lever stays in reach and the rod carries the bolt |
Check these before you order bolts
- Exit doors: the International Building Code does not permit manually operated flush or surface bolts on doors in the means of egress, apart from narrow exceptions.
- If both leaves of a pair are needed for exit, leave these bolts off and use exit hardware on both leaves.
- A key must never be needed to leave through an exit door.
- Fire doors: the door's certificate decides which bolts it may carry. The flush bolts we list are hand operated.
- Local rules differ, so confirm with the authority for your project.
- The floor socket keeps dirt out of the bolt hole. Without one the bottom bolt stops short.
- Dust Proof 01 and Dust Proof 02 list 16mm, so have the bolt diameter confirmed against it.
- Top strike: state whether you need it supplied, and what the frame head is made of.
Surface bolts are a different order
A surface bolt fixes to the door face and needs no cutting. It does not replace a flush bolt on a pair, because it sits on the face of the leaf and can be seen. Note that the number does not always tell you the type: FB012 is a barrel bolt, not a flush bolt, and DS011 is a double ball catch, not a door stopper.
| Model | Type | Listed |
|---|---|---|
| BH15 | Barrel bolt | 80mm or 100mm long, 38mm wide, 1.2mm stainless steel |
| BH16 | Flat slide bolt | 70 x 48mm, 1.0mm stainless steel |
| BH59 | Surface slide bolt | 304 stainless steel, satin finish |
| FB012 | Barrel bolt | 3 to 10 in long, 30mm wide, stainless steel |

- Which leaf of each pair is active.
- Finish, one code for the whole opening.
- Whether any door is an exit or fire door, with its certificate.
Questions buyers ask
How many flush bolts does a double door need?
Two, both on the inactive leaf: one into the frame head and one into the floor. The active leaf latches into the inactive leaf, so it takes none.
Does each leaf of a pair need its own door stopper?
Yes. Each leaf swings on its own and can strike a wall. Order two stops per pair.
What length of flush bolt do I order?
FB001 and FB017 list 8, 10, 12 and 24 in. Send the door height and where the lever should sit. For a tall pair, FB016 uses an extension rod, so state the floor to frame head height.
Can I use a flush bolt on a single door?
A flush bolt holds an inactive leaf in a pair, so a single door has no use for one. For a single door that needs bolting from inside, look at a surface bolt, and keep it off any exit door.
Does a door with a closer still need a stop?
Yes. A closer shuts the door but does not stop it at the end of its swing.
Does the floor stop fix to a tile floor?
It screws down, so the fixing depends on the floor. State tile, concrete or timber on the order and check for underfloor heating or pipes before anyone drills.
