DIY Shed Security Bar (in 10+ Easy Steps!)

One of the easiest places for a burglar to break into is your shed. I have personally had a shed security bar save me from a robbery on one occasion.

The shed security bar is an important accessory. Sheds are typically built from wood, so the security bar is a strong beam that runs across the top edge of the door, which can be padlocked to deter intruders. The security bar not only strengthens the lock on a shed door but also provides an additional layer of protection against burglars and other criminals who might try to break into your shed by force.

A lot of people do not even know that there are many types of shed security bars available to them, so they might only go for the most popular one. Most don’t even know there is an easy do-it-yourself option and doing some research can save you time, money, and effort in the long run.

Below well be going through the steps to do it yourself.

Why Do You Need a Shed Security Bar? 

Outdoor areas are one of the favorite places thieves target. This is because it is easy to find valuable and sellable items like bikes, sports items, machinery, tools, gardening equipment, etc., in sheds. According to the insurance industry, the items in a shed on average amount to more than a thousand dollars. The contents of your shed must cost around this figure too. (1)

Since normally there are no other security systems in a shed, the contents of a shed are extremely vulnerable to being stolen. This makes protecting your shed with a shed security bar an really good idea. 

1. Choose the Material 

The shed security bar could be made of wood or metal; the material does not affect the amount of security offered by the bar. This is, of course, assuming that the bar is strong enough to withhold any attempts to break it. 

The shed security bar could be made of wood or metal; the material does not affect the amount of security offered by the bar. This is, of course, assuming that the bar is strong enough to withhold any attempts to break it. 


When you’re making a shed bar, using a metal bar can make your job much easier. This is because it is easier to use a lock with a metal bar. Whereas for a wooden bar, you would have to make a locking handle into the brackets, which might make the job more complicated. You might buy a security bar lock bracket, but the added complexity of the bracket might compromise its ability to prevent break-ins. 

Choosing a metal bar can allow you to build a shed security bar that has the minimum number of pieces; the fewer the pieces in the bar security system, the harder it is to break apart. (2)


If you value aesthetics and want the bar to match the wood of the shed, or if you already have a wooden bar, or if you have tools that work with wood but not with metal, or if you wish to make a wooden shed security bar for any other reason, you can also use the general instructions in this article to build a wooden shed security bar. 

2. Choose the Type 

There are two types of shed security bars you can build; the hook bar and the sliding bar. Both of these types of security bars provide adequate security. But based on your specifications, one may be better for you than the other. Let’s take a look at what each of these types is like. 

The Hook Bar 

The hook bar is exactly what it sounds like; it is a bar bent to one end at 90 a degree angle. A slide bar cannot be placed where there is not enough space beside the door to slide the bar over. In such a situation, a hook security bar is a perfect option because it is placed and removed by turning it like a door. However, a hook bar is not as simplistic as a sliding bar. It needs to be made into a hook either by curving the metal or by welding a different piece of metal on the bar. 

The Sliding Bar 

A sliding bar is a relatively simple option than a hook bar. However, it requires there to be enough space next to the door to slide the bar open. A reason to choose a slide bar, other than simplicity, is that a sliding bar can be as thick as you want. Since a sliding bar does not need to be bent, you can use any bar. You can even use a hollow bar to make your slide bar. 

3. Choose the Bracket 

The type of bracket you need depends on the type of shed security bar you want to make. 

The curve of a hook security bar keeps it from moving in one direction. To lock it in place, you only need to restrict its motion in the other direction. This can be done by putting a lock on the side other than the curved side. The size of the lock alone will keep the bar from coming off: the bar does not have to be locked to anything.  

A sliding bar is different, however. Since it can freely move in both directions, it has to be locked to the bracket. Hence, for a sliding bar, both the bar and one of the brackets should each have a hole where you can put the shackle in.  

For a hook bar, any bracket that allows the bar to pass through will do.

4. Gather the Equipment and the Materials 

Here’s a list of materials you need to build a DIY shed security bar. 

  1. A metal bar 
  2. 2 brackets 
  3. Carriage bolts, nuts, and washers 
  4. A drilling machine 
  5. An adjustable spanner 
  6. A metal-cutting saw 
  7. A lock 
  8. A pencil 

5. Measure Your Door 

Your DIY shed security bar has to be of an appropriate length based on your door. In this step, you will figure out where the brackets should go and what length the bar should be.  

Measure the width of your shed door and add 2 to 4 inches on both sides. This is the width of your bar should be. You may use this length to cut the metal bar to the appropriate length or buy a bar of this length. 

It is a good idea to know accurately how long a bar you need before cutting or buying one so you don’t have to cut again or go to the market again. If you’re building a hook bar, you will need to buy a bent bar from the market. You may cut the bar to the appropriate length later yourself, however. 

6. Marking 

This is the step where you mark where the brackets will go and where the drill holes should be. Once you have your bar cut to the appropriate length, you can mark where the brackets should go. Hold the brackets with the bar against the width of the door such that the ends of the bar touch the wall on each side. Now mark the location of the brackets.  

After this, you can place the brackets on their location one by one to mark where the drill holes should be on the wall. In order to increase the accuracy in the positioning of the holes, fill the entire area of the holes in the bracket. If the screws are accurately positioned, it will allow the brackets to attach firmly, making the DIY shed security bar sturdy. 

7. Drilling in the Wall 

Once the locations have been marked, it’s time to drill the holes. One of the most important things you should consider before drilling a hole is the size of the bit. The drill bit should be the same size as the size of your screws. 

Make sure you drill accurately where you marked. Making a small hole with a nail at the center of the mark may increase your drilling accuracy. 

8. Drilling in the Bar 

Unless your bar already has a hole for a lock, you also have to drill a hole in your bar in this step. 

You do not need any extra-hard special-purpose drilling bits to drill in metal. Any general-purpose drilling bit will do the job. Make sure you wear a pair of protective glasses before you start drilling. 

Make a mark where you want the lock hole to be and drill a hole. 

9. Drilling in the Brackets 

If you’re building a sliding security bar and your brackets do not have a hole, this is the part where you drill a hole in it. 

Make sure this hole is drilled from the same bit or is the same size as the hole in the bar. You also want this hole to be at the same lateral position as the bar. 

10. Install the Brackets 

Once the bar and the brackets are ready, and the holes have been drilled, you can install the brackets. Place the brackets in their marked positions and use carriage bolts so that they can’t be unscrewed from the outside. Make sure the bolts are heavy-duty so that they do not come off easily. 

You will have to put in the carriage bolts from outside and put the nuts from inside the shed. 

If you’re making the sliding security bar, make sure you place the bracket with the hole on the handle side of the door.

11. Mount the Bar 

Once you have installed the brackets, the bar is ready to be mounted. Insert the bar from both the brackets, lock it in, and you have added an extra layer of security for your belongings in the shed. Make sure the bar cannot come off in any way when locked. 

12. Test your Security Bar 

You can test the security bar from all angles. You can try giving it a good jerk to make sure the brackets are screwed tightly. You can try to unscrew the carriage bolts with a spanner from outside. You also may, if you don’t mind scratching the wall a little bit, try to use a crowbar against the bolts. Most likely, they won’t come off because they have nuts on the other side of the wall.

Whether you choose to build a DIY hook security bar or a DIY sliding security bar, once you have made a security bar this way, you can bet thieves are going to have some real trouble stealing from you. Make sure you choose good materials so the security bar cannot be compromised. Use carriage bolts so they cannot be unscrewed from outside and place the brackets tightly so they don’t shake and loosen over time.
