The Definitive Guide To Morgan 4 Roll Cages From Safety Devices
When it comes to enhancing safety without compromising the classic aesthetic of your Morgan 4, investing in a roll cage from Safety Devices is one of the smartest upgrades you can make. Whether you’re prepping for hill climbs, sprint events, or just want additional rollover protection during road driving, these bolt-in cages have been designed specifically with Morgan models in mind. In this guide, we’ll walk you through our full range of Morgan 4 Safety Devices roll cages and help you understand the subtle differences between each option.
Why Fit a Roll Cage to Your Morgan?
Classic sports cars like the Morgan 4 may be fun and nimble to drive, but they weren’t exactly designed with modern crash protection in mind. A bolt-in roll cage adds crucial rollover protection, significantly improving occupant safety in the event of a crash or track incident. It also helps stiffen up the chassis, which is particularly useful for track use or spirited road driving.
The Safety Devices range of roll cages for Morgan vehicles are engineered to be as discrete as possible, preserving the car’s classic lines while integrating strong, FIA-compliant designs where applicable. With no need for permanent body modifications, these cages are an ideal choice for owners who want protection without compromising originality.
Regulatory Approvals and Motorsport Compliance
It’s important to note that while our Morgan roll cages comply with the latest UK regulations for circuit racing, they are not fully FIA/MSA approved. This means:
- Circuit Racing Ready: Designed and approved for use on UK racing circuits, ensuring you meet local safety standards.
- Not Universal: These roll cages cannot be used for all motorsport events globally due to FIA/MSA restrictions.
Before any race, always confirm that your vehicle and safety equipment meet the specific regulations of the event you’re entering.
Understanding FIA and MSA Standards
If you’re unsure about whether you need an FIA- or MSA-approved roll cage, here’s a quick breakdown of the differences:
- FIA Standards – The Fédération Internationale de l’Automobile (FIA) sets global safety standards for motorsport. FIA-approved roll cages are rigorously tested and required for high-level international competitions and professional racing.
- MSA Standards – Motorsport UK (formerly MSA) regulations apply to racing events within the UK. While closely aligned with FIA standards, MSA-approved roll cages meet national motorsport requirements and are suitable for competitive UK-based racing.
For international or professional-level racing, FIA-approved roll cages are mandatory. For UK motorsport events, MSA-approved roll cages are often sufficient. For track day enthusiasts, non-approved roll cages offer excellent protection without the need for full certification.
Morgan Plus 4 Bolt-In Rear Roll Cage
This cage is purpose-built for standard Morgan Plus 4 models. It bolts into the rear of the car and provides a substantial boost in rollover protection without altering the original interior layout too much.
Key Features:
- Designed specifically for the Morgan Plus 4
- Bolt-in installation
- Retains access to most of the rear cabin area
- No welding or permanent modification required
Ideal for drivers who want increased protection for spirited driving or fast road use while retaining the character of their car.
Morgan Plus 8 and Plus 4 with T16 Engine Roll Cage
This version caters to the slightly different body and interior layout of Morgan Plus 4 and Plus 8 models fitted with the T16 engine. It ensures a proper fit where other cages might run into clearance issues.
What’s Different?
- Custom-designed mount points to clear the T16 engine components
- Optimised for models with unique engine bay and rear cabin layouts
- Maintains ease of access and compatibility with trim and carpet
This is the one to go for if your Morgan is fitted with the 2.0L Rover T16 powerplant.
Morgan Plus 4 and 4/4 (4-Seater) Rear Roll Cage
This roll cage is tailored for Morgan Plus 4 and 4/4 models configured with four seats. Since the rear seat area differs from the two-seat versions, this cage has slightly revised mounting points and tubing placement.
Why This Cage?
- Specifically designed for 4-seat configurations
- Preserves rear passenger space
- Still provides full rollover protection for the front occupants
This is the perfect solution for Morgan owners who occasionally carry rear passengers but still want the peace of mind of extra safety up front.
Morgan Plus 4 (2010–2020) Bolt-In Rear Roll Cage
If you’ve got a newer-generation Morgan Plus 4 built between 2010 and 2020, this is the cage you’ll want. It’s shaped to fit around the subtle design updates and chassis changes that came with the later models.
Highlights:
- Compatible with 2010–2020 Plus 4 models
- Sleek bolt-in design to follow modern trim contours
- Allows for use on the road and track with minimal compromise
This version balances modern design with traditional safety needs and is a great choice for both classic purists and weekend racers.
Plus 4 and Plus 8 Chassis Rear Roll Bar
This is a more minimal roll bar design intended for drivers who want some protection but don’t need a full rear cage. It’s compatible with both Plus 4 and Plus 8 chassis and mounts directly to the rear for added structure.
Best For:
- Road-focused drivers wanting a discreet safety upgrade
- Those looking to improve torsional rigidity without a full cage
- Owners not looking to install a full rear interior kit
If you’re after just a rear hoop for visual flair and peace of mind on the road, this is the one to go for.
Which Roll Cage Is Right For You?
Choosing the right cage really depends on your car’s model, generation, and how you plan to use it. Whether you’re a Sunday cruiser or an enthusiast heading to Goodwood or a hill climb, there’s a Safety Devices cage built for your Morgan. All of these products have been tried and tested by owners and enthusiasts, and they come from one of the most trusted names in roll cage engineering.

The Importance of Professional Installation
When it comes to motorsport safety, every component must be installed with precision. Even though our Safety Devices Morgan roll cages are designed with bolt-in fitment, professional installation remains critical. A roll cage that isn’t installed correctly—even one that bolts in—can compromise the structural integrity of your vehicle and may fail to meet the strict motorsport regulations required for safe racing.
A certified installer brings the expertise needed to ensure every bolt is securely fastened and that the roll cage is perfectly aligned with your Lotus chassis. This meticulous installation guarantees that the cage will perform as intended, providing maximum protection in the event of a crash or rollover while upholding regulatory standards. Trusting a professional with your installation is an investment in safety that can make all the difference on the track.
Road Use vs Track Use – What to Consider
One of the most common questions we hear from Morgan owners is: Do I need a roll cage if I only use my car on the road? The short answer is no, but there are plenty of good reasons to consider it.
A roll cage or bar increases chassis stiffness, especially in older vehicles like the Morgan 4 that use a classic ladder frame and wood/aluminium bodywork. This added rigidity can improve handling feel, especially under hard cornering or braking. For road-going cars, a rear roll bar is a discreet way to add safety without altering the character of the vehicle.
For competition or track use, a full bolt-in rear roll cage is a must. It provides rollover protection that could be life-saving in the event of an incident. And since all Safety Devices cages are precision-manufactured and designed for specific Morgan models, they won’t compromise your car’s layout or access.
What About Interior Trim and Roof Fitment?
One concern with adding a roll cage to a Morgan is whether it will interfere with your car’s roof or interior trim. Safety Devices has taken this into account.
All Morgan roll cages in our range are designed to fit inside the factory dimensions of the car. That means you’ll retain the use of your soft top or hardtop in most configurations, and only minimal trimming (if any) is required on interior trim pieces.
For cars with bespoke trim work, we recommend a professional installation with careful measurements. But in most cases, fitting these cages is a bolt-in affair that’s relatively straightforward and reversible if needed.
