The door material is one of the first things to check before you order any entry hardware. It sounds obvious, but matching the right kit to the wrong door is one of the most common reasons jobs go sideways. A maglock that fits a timber frame beautifully might be a poor choice on a frameless glass entrance. An electric release that's perfect for a metal door may not suit uPVC at all.
This guide breaks down how door construction and configuration affect your choice between maglocks, electric releases, brackets, and fitting methods. We'll cover wooden, metal, glass, and uPVC doors separately, with practical guidance for each. Whether you're an installer specifying for a client or a facilities manager sourcing the right setup, this helps you choose an access control systems kit that actually fits the door in front of you.
Why Door Material Drives the Decision
Every locking method needs something to fix to. The door's material, the frame, the thickness, and how the door swings all decide what you can mount and where. Before anything else, the material affects two key choices:
- Maglock or electric release? One holds the door shut with an electromagnet; the other controls the latch on an existing mechanical lock.
- What brackets do you need? Glass and inward-opening doors often need additional brackets to mount hardware that a standard timber door wouldn't require.
Get the material right first, and the rest of the kit selection becomes far simpler. Here's how each door type behaves.
Wooden Doors
Timber is the most forgiving material to work with, which is why so many installs go smoothly on wooden doors. There's plenty of solid material to fix into, and the frame usually gives you room for both surface-mounted and recessed hardware.
Locking options
- Maglocks mount cleanly to a timber frame using the supplied bracket and armature plate. The flat surface and solid fixing points make this straightforward.
- Electric releases suit wooden doors well, since you can mortice the strike into the frame to work with the existing mechanical lock. This keeps a key backup and hides the hardware.
Both methods work, so the decision usually comes down to whether the door is on an escape route (favouring a fail-safe maglock) or an internal door where a discreet, fail-secure release is tidier.
Fitting considerations
- Check the door thickness before specifying a release, so the strike sits correctly.
- For inward-opening doors, you may need a Z and L bracket to mount a maglock on the pull side.
- Confirm the timber is solid where you're fixing, not a hollow core panel that won't hold the load.
Metal Doors
Metal doors, including steel and aluminium-framed units, are common on commercial premises, fire exits, and external entrances. They're robust and often high-traffic, which makes durable hardware a priority.
Locking options
- Maglocks are a strong choice here. With no moving parts and high holding force options, they cope well with heavy metal doors and frequent use.
- Electric releases can work, but it depends on the frame profile and whether there's room to recess the strike. Narrow aluminium profiles can limit your options.
Fitting considerations
- Aluminium and narrow-stile doors may need specific brackets or a slim-line release designed for tight profiles.
- Drilling and fixing into metal needs the right tools and fixings, so factor that into the job time.
- Heavy fire doors on escape routes almost always call for a fail-safe maglock with a break-glass switch to meet UK fire safety rules.
- Check whether the door has a door closer fitted, as this affects how the maglock holds and releases.
Glass Doors
Glass entrances look smart, but they're the trickiest to fit. You usually can't drill into the glass itself, so your fixing options depend entirely on whether the door is framed or frameless.
Framed glass doors
If the glass sits within an aluminium or metal frame, you can often mount hardware to the frame much like a metal door. A maglock fixes to the frame head, with the armature plate on the door's frame section.
Frameless glass doors
Frameless glass needs specialist mounting. You can't fix straight into the glass, so a maglock kit relies on U-brackets or glass door brackets that clamp around the leaf without drilling. These let you mount the armature plate securely on a frameless panel.
Fitting considerations
- Confirm whether the door is framed or frameless before ordering, as it changes the bracket entirely.
- Frameless doors usually need a U-bracket or glass clamp to take the armature plate.
- Electric releases are generally not suited to frameless glass, since there's no frame to recess a strike into.
- Patch fittings and floor springs on glass doors can complicate where the lock sits, so measure carefully.
Maglocks are typically the go-to for glass doors because they avoid drilling into the leaf. The right glass bracket makes the difference between a clean install and a non-starter.
uPVC Doors
uPVC doors are everywhere on smaller commercial units, home offices, and residential entrances. They're a sensible, affordable choice, but the material brings a few specific considerations.
Locking options
- Maglocks can be fitted to uPVC, but the frame's strength matters. uPVC frames are hollow in places, so you need solid fixing points and often brackets to spread the load rather than relying on the plastic alone.
- Electric releases can work with uPVC multipoint locking systems, but compatibility varies. Many uPVC doors use a multipoint lock that doesn't pair simply with a standard release strike.
Fitting considerations
- Check whether the door uses a multipoint locking mechanism, as this affects whether an electric release is practical.
- uPVC flexes more than timber or metal, so fixings must reach solid reinforcement within the frame.
- Brackets are often needed to mount a maglock securely without stressing the plastic.
- For lighter internal uPVC doors, a maglock with the right bracket is frequently the simplest reliable route.
uPVC takes a little more thought than timber, mainly around finding solid fixing points. When in doubt, confirm the door's locking mechanism and frame construction before you order.
What to Gather Before You Order
A few minutes of checking saves a wasted trip and a returned product. Before you select an access control kit for your door type, gather this information:
- Door material — wooden, metal, glass (framed or frameless), or uPVC.
- Door configuration — does it open inward or outward? This affects bracket choice.
- Frame type and profile — solid timber, narrow aluminium stile, hollow uPVC, and so on.
- Existing lock — is there a mechanical lock or multipoint mechanism you want to keep?
- Escape route status — is the door on a designated fire escape? This decides fail-safe versus fail-secure.
- Traffic level — how heavily used is the door day to day?
- Holding force needed — perimeter and heavy doors need stronger locks than internal ones.
With those answers in hand, matching the door to the right kit becomes a quick, confident decision rather than a guess.
Common Mistakes to Avoid
- Ordering before checking the door. Material and configuration decide what fits. Confirm them first, every time.
- Forgetting brackets on glass and inward-opening doors. A maglock without the correct bracket simply won't mount where it needs to.
- Fixing maglocks into hollow uPVC. Without solid reinforcement, the lock won't hold reliably.
- Trying to recess a strike into a frameless glass door. There's no frame to work with, so an electric release rarely suits.
- Ignoring escape requirements on metal fire doors. Fire exits need fail-safe locking and a break-glass switch to stay compliant.
- Overlooking the door closer. On metal and uPVC doors, a closer affects how the lock seats and releases.
Matching the Kit to the Door
Door material shapes nearly every other choice in an access control install. Timber gives you flexibility for both maglocks and releases. Metal favours durable maglocks, especially on fire doors. Glass leans on maglocks with the right brackets, particularly when frameless. uPVC works too, as long as you find solid fixings and check the existing lock.
Confirm the material, configuration, and escape status first. From there, choosing the right hardware and brackets is straightforward. Get that order right, and you'll fit a system that works cleanly and lasts.
