retractable bollards
MSA Bollards’ retractable bollards are designed to provide secure vehicle access control while maintaining the flexibility to open an area when required. When raised, they provide a strong physical deterrent. When lowered, they sit flush with the ground, allowing unrestricted pedestrian or vehicle movement.
From fully automatic electric systems to heavy-duty pneumatic and assisted manual models, our retractable range is engineered for Australian conditions and built for commercial reliability.
Why do you need a retractable bollard?
- You need to protect a thoroughfare from unauthorised acces
- You don't need protection 24/7 but have nowhere to store the bollard
- You want to minimise the OH&S risk of removing heavy bollards
Sentry SPU
Secure Manual Operation with Clutch-Lift Mechanism
The SPU Retractable Bollard features a clutch-lift key system that allows quick and controlled manual operation. Designed for reliability and secure locking, the SPU offers an alternative manual solution where simplicity and positive engagement are priorities.
The clutch-lift mechanism provides a more controlled raising action compared to basic manual systems, improving usability while maintaining mechanical durability.
SPU bollards are well suited to:
Shared access zones
Restricted parking areas
Commercial driveways
Properties requiring controlled but infrequent vehicle access
With no reliance on power supply or air systems, the SPU provides dependable access control in a self-contained design.
Sentry MK2
Simple, Cost-Effective Access Control
The MK2 Manual Retractable Bollard is a straightforward and economical solution for controlled vehicle access. Operated using a T-handle lifting tool, the MK2 locks securely into position when raised and retracts flush into the ground when access is required.
Its simplicity is its strength — with no electrical or pneumatic components, the MK2 offers minimal servicing requirements and dependable long-term use.
The MK2 is ideal for:
Low-frequency access points
Private driveways
Light commercial premises
Budget-conscious projects
This model provides effective vehicle control where automation is not necessary. It is a practical and durable solution for sites that require occasional access restriction without the cost of powered systems.
Sentry MK3
Reduced Effort Manual Operation
The MK3 Gas Strut Assisted Retractable Bollard is designed for sites that require manual control but want to reduce lifting strain and improve ease of use.
Unlike standard manual bollards, the MK3 incorporates a gas strut mechanism that assists when raising the bollard from its recessed position. This significantly reduces physical effort and improves workplace safety compared to conventional fully manual systems.
The MK3 is well suited to:
Schools and community facilities
Strata properties
Service vehicle access zones
Locations with moderate usage frequency
It provides the cost advantages of a manual system while delivering improved ergonomics and smoother operation. When lowered, the bollard sits flush with the surrounding surface, maintaining a clean and unobstructed finish.
For sites that need reliability without automation, the MK3 strikes a strong balance between performance and affordability.
Sentry MK4
Heavy-Duty Performance with Reliable Pneumatic Actuation
The MK4 Pneumatic Retractable Bollard delivers dependable performance using compressed air to raise and lower the bollard smoothly and efficiently. Pneumatic systems are known for their mechanical simplicity, durability and consistent operation over long periods.
Unlike fully electric motor-driven systems, pneumatic actuation reduces the number of moving parts exposed to wear. This makes the MK4 an excellent choice for sites wanting reliable performance with streamlined servicing requirements.
Pneumatic bollards are ideal for:
Commercial premises with regular access cycles
Warehouses and logistics facilities
Controlled access industrial sites
Multi-user properties
The MK4 provides strong vehicle control while maintaining ease of operation. Its robust in-ground design ensures long-term durability in Australian conditions, and it is suitable for both new installations and retrofit applications.
If you want smooth automated movement with a focus on mechanical reliability, the MK4 Pneumatic Retractable Bollard is a proven performer.
Sentry electric
Automated Convenience with Commercial-Grade Performance
Our Electric Retractable Bollards represent the most advanced and user-friendly solution in our range. Designed for high-traffic commercial environments, these bollards raise and lower at the push of a button, via remote control, key switch, swipe access, intercom integration or automated access control systems.
Electric operation eliminates manual lifting entirely, making them ideal for sites with frequent daily use or strict OH&S requirements. They provide smooth, controlled movement and can be integrated into existing security infrastructure, including boom gates, card readers, number plate recognition systems and building management systems.
Electric bollards are particularly suited to:
Commercial and industrial driveways
Car park entrances
High-security access points
Residential complexes
Government and infrastructure facilities
Electric with Pneumatic Configuration Option
Our electric systems can also be configured to operate using pneumatic actuation where required. This allows you to combine automated control with the mechanical simplicity and reliability of compressed-air operation.
This hybrid flexibility means you’re not locked into one system type — we can tailor the actuation method to suit your site conditions, usage frequency and maintenance preferences.
If you require frequent operation, remote activation and seamless access control integration, Electric Retractable Bollards are the premium solution.
Choosing the Right Retractable Bollard
Selecting the right retractable bollard depends on:
Frequency of use
Required level of automation
Integration with existing access control systems
Budget
Site conditions and infrastructure
For high-use, security-integrated environments, Electric or Pneumatic systems provide the greatest convenience and long-term efficiency.
For moderate-use locations, Gas Strut Assisted models reduce manual strain.
For occasional-use applications, Manual and SPU systems offer cost-effective reliability.
