Increase the existing security of your property even further by adding additional door security products, such as a security bolt or T-bar door latch.
Why upgrade with additional door security?
Installing extra hardware is a practical way to reduce vulnerability in a door or window. A standard lock covers the main opening, but things like hinge reinforcement, secondary bolts, security chains or T-bars protect against further entry methods. Our additional door security range allows you to upgrade affordably and effectively. At DG Supplyline you’ll find accessories that fit many door types and materials.
What kind of door reinforcement hardware do you need?
We carry a wide range of items to strengthen your door. Our range includes heavy-duty bolts, for example the ERA 838-32 Security bolt, slidebolts and tower bolts. Each of our door security accessories is selected to suit both domestic and commercial setups. Many models are available in polished chrome, satin brass or black finishes so you can match your existing set-up.
How to choose and install the right accessories
Start by assessing your door’s vulnerabilities. Are the hinges exposed? Is the weak point the bottom of the door? Perhaps the existing deadlock is good, but an additional bolt would make forced entry much harder. For instance, adding a slide bolt to the inside face adds one more point of resistance. If you already have a robust lock, adding a chain guard gives you a limited-opening option for ventilation or viewing without full access. Because we integrate with our other categories you may want to check accessories from our multipoint door locks and cylinder locks ranges for comprehensive reinforcement. Choose accessories that are compatible with your door material, frame type and needs. If you need help, give us a call and we can guide you to the right additions for your door or window.

FAQs
What is additional door security?
If a door is vulnerable, you might need hardware beyond your primary lock. These include bolts, chains, guards and T-bars. Each adds extra resistance to forced entry and reinforces a door’s weak points.
How do I decide which door security accessories I need?
Look for the weakest element of your door and then select reinforcement hardware that addresses that specific vulnerability. If there are no obvious points, then you could apply additional door hardware in multiple laces. For example, an extra bolt or hinge protector hinge. Or a chain if you want partial opening.
Can I install these accessories myself?
Many items are straightforward to install with a screwdriver and appropriate screws. However, if you’re unsure about drilling into your frame or selecting compatible hardware, professional fitting is best.
Do these products work with uPVC or composite doors?
As long as the accessory is compatible with the door material and the fixing points are secure. Be sure to check the specification and measurements before purchasing.
Will adding bolts and chains void my door warranty?
Provided the accessory is correctly installed and doesn’t interfere with your door’s main lock or frame seal. Always check your manufacturer’s warranty terms. Sometimes house insurance might specify that additional security be professionally installed.
Do you provide support if I am unsure which accessory to choose?
