Overview
The F3 Square Compact GRP Cabinet is designed for professionals who require a mid-sized enclosure that delivers both generous internal capacity and practical installation. Its near-square footprint and 500 mm depth make it suitable for a wide range of environments, from rural sites to dense urban infrastructure.
Built to withstand demanding outdoor conditions, the F3 provides long-term durability, security, and stability for public, commercial, and industrial applications across the UK.
Engineered for Strength and Reliability
The cabinet is constructed from high-grade Glass Reinforced Plastic (GRP), reinforced with 300, 450, and 600 gsm Chopped Strand Mat (M705). This multi-layer reinforcement delivers excellent strength, rigidity, and impact resistance.
A Crystic® GT-600 BS226 Green gelcoat finish provides marine-grade protection against UV exposure, heavy rainfall, frost, and airborne pollutants. Internally, the CrysticROOF resin system enhances bonding strength, resulting in a rigid enclosure that resists cracking or distortion under load.
Security and Protection
The F3 is fitted with a Yale 77 Traditional Nightlatch for primary access control, supported by a 10 mm zinc-plated spring bolt for additional locking security. ZOO ZHSS232 stainless-steel hinges ensure smooth, corrosion-resistant operation.
Scapa 3259 closed-cell foam compression tape seals the enclosure, helping to prevent water, dust, and air ingress. This layered protection makes the F3 suitable for installations where environmental control and equipment security are essential.
Professional Interior Design
Internally, the cabinet includes a 12 mm CE-marked ALPHAPLY plywood base for mounting heavy equipment, combined with 3.6 mm eucalyptus-faced plywood lining for clean, smooth internal walls.
This construction provides a stable mounting surface and a bright, professional interior finish, supporting safe and efficient work on electrical, mechanical, or control systems.
