Commercial Door Security Upgrade – Split Spindle Handles, 3 Star Lock and Latch Guard Installation
Commercial buildings often have doors that are used regularly by staff but are positioned away from the main office or reception area. These access points can become a weak spot if the handles are worn, the lock is outdated, or the door can be opened from outside without proper control.
This week we were asked by a commercial customer to carry out a security upgrade on an outward opening access door. The door was located on a lower floor of the building and sat out of the direct line of sight of staff working in the office space above. Because of that, the customer wanted the door made more secure while still allowing safe escape from the inside.
The Problem With the Existing Door Setup
The existing handles had become worn and the customer wanted to reduce the risk of anyone being able to gain access from outside without permission. On commercial buildings, this is especially important where a door is:
- Out of sight of reception or office staff
- Used by employees during the day
- Left on the latch while the building is occupied
- Outward opening and therefore more exposed at the closing edge
When a door is outward opening and positioned away from regular staff view, it makes sense to strengthen both the locking side and the external hardware so that access is only possible when it has been granted.
Security Upgrade Carried Out
To improve security on this commercial door, we completed the following upgrades:
- Replaced the worn handles with new inline handles
- Installed a split spindle setup
- Fitted a 3 Star Sold Secure Diamond approved euro cylinder
- Added a latch guard to protect the outward opening door
- Maintained safe internal egress for emergency escape
Why Inline Handles Were Installed
The original handles were tired and worn from use. We replaced these with new inline handles to give the door a cleaner, more secure and more reliable setup. On commercial entrances and staff doors, worn handles can create slack, poor operation and reduced confidence in the overall security of the entrance.
Freshly fitted handles also help support the rest of the locking hardware and improve the operation of the door day to day.
What a Split Spindle Does
A split spindle is a very useful upgrade on a commercial door where you want staff to be able to exit safely from inside, but do not want the external handle to simply operate the latch from outside.
With this type of setup:
- The inside handle still allows safe exit
- The outside handle does not retract the latch unless authorised access is used
This makes it much harder for anyone to enter from outside without permission and is ideal for staff doors, office access doors, rear entrances and lower level commercial access points.
3 Star Sold Secure Diamond Lock Upgrade
As part of this job, we fitted a 3 Star Sold Secure Diamond euro cylinder. This type of lock offers a high level of protection and is designed to resist common methods of attack used against euro cylinders.
Benefits of a high security 3 star cylinder can include protection against:
- Lock snapping
- Picking
- Bumping
- Drilling
- Forced attack on the cylinder
For commercial customers, upgrading to a better cylinder is often one of the most cost-effective ways to improve the overall security of an entry door.
Why a Latch Guard Was Important on This Door
This was an outward opening door, so we also fitted a latch guard. This is an important extra layer of protection because outward opening doors can sometimes leave the latch area more exposed than inward opening doors.
A latch guard helps protect the gap between the door and the frame, reducing the chance of someone trying to:
- Slip the latch
- Attack the door with hand tools
- Manipulate the opening edge from outside
On a commercial property, especially one with a door positioned away from staff view, this is a sensible and practical upgrade.
Safe Escape Still Matters
Whenever security is upgraded on a commercial building, it is important to make sure that the door still allows safe egress from inside. Security should never come at the expense of people being able to leave the building safely and quickly when needed.
In this case, the finished setup gives the customer both:
- Improved control over access from outside
- Safe escape from inside
Ideal for Offices, Staff Doors and Commercial Units
This type of door security upgrade is ideal for many commercial settings, including:
- Office access doors
- Staff entrances
- Rear doors
- Lower ground floor entrances
- Commercial units
- Shops and service entrances
If your building has a door that is out of direct sight of staff, has worn handles, or could benefit from better control over who can enter from outside, a security upgrade like this can make a major difference.
