Understanding the structural requirements and installation process is crucial, as the Trellidor Trojan II T1000 (Trojan S2 Pro) must be fitted correctly to maintain its official LPCB LPS 1175 Level 2 (SR2) certification. The system features a robust, fully framed construction engineered to integrate seamlessly into a building's architecture while providing maximum resistance against determined attacks.

Approved Substrates & Site Preparation

To ensure the integrity of the Secured by Design rating, the grille must be installed directly into a secure reveal aperture. The site must be prepared to accommodate fittings into one of the following approved structural substrates:

• Reinforced concrete
• Solid brickwork
• Concrete block-work
• Structural steelwork

The Installation Process

1. Structural Anchoring

The fully framed system is designed to be secured firmly on all four sides. To meet safety and security standards, installers must use a minimum of an approved M8 Tensile Grade 12.9 steel bolt fixing. This heavy-duty anchoring binds the grille to the substrate, preventing the frame from being levered or forced out of the structural opening.

2. Top Track Mounting

The grille operates on a finely balanced top-hung system. A galvanized steel U-channel top track is securely mounted to the structural lintel or steelwork above. This track enables the heavy-duty door sections to glide effortlessly. For added attack resistance, a galvanized steel shroud is fitted to overlap the U-channel on the external attack face, protecting the top rollers from tampering.

3. Recessing the Bottom Channel

A standout architectural feature of this grille is its completely trip-free threshold, which requires groundwork during installation. The galvanised steel bottom U-channel must be recessed beneath the floor surface so that it sits perfectly flush with the Finished Floor Level (FFL). The recessed channel has an internal dimension of 25mm, which neatly houses the solid steel sill guides and enclosed steel bearings that run out of sight below the floor.

4. Locking System & Shroud Alignment

Once the framework is set, the secure locking jambs are aligned. Three CR12 stainless steel angled shrouds are strategically positioned to overlap the vulnerable areas of the door. This ensures the internal Emergency Escape (EMESC) lock box, anti-drill discs, and 4-point deadlocks operate smoothly while remaining impenetrable from the outside.

Bespoke Installation Scenarios

• Corner Applications: The system is fully certified for custom installations requiring the grille to be fitted at angles between 90° and 135°, making it perfect for bespoke entranceways or non-linear architectural footprints.
• Concealed Storage Recesses: Wall cavities or lockable storage recesses can be incorporated during the building phase. This allows the stacked grille to slide back and be completely hidden from public view when opened during regular trading hours.

Note: All Trellidor product components are pre-treated for enhanced corrosion resistance and finished with a premium UV-resistant polyester powder coating to extend the lifespan of the grille.

Conditions of Warranty

To maintain the validity of your warranty and the LPCB Level 2 (SR2) certification, the following conditions must be met:

• Professional Installation: The grille must be installed by trained, certified technicians strictly according to the approved substrate fixing methods (minimum M8 Tensile Grade 12.9 steel bolts).
• Intended Use: The warranty covers faults occurring during the intended use of the product. It does not cover damage resulting from deliberate physical attacks, vehicle impacts, structural building shifts, or severe natural disasters.
• Original Purchaser: The warranty is valid only for the original purchaser and is not transferable. Proof of purchase is required for all claims.
• Unauthorised Alterations: Any modifications, unauthorised repairs, or use of non-approved locking cylinders will immediately void the warranty.

Recommended Maintenance Regime

To ensure smooth operation and keep your warranty fully intact, Trellidor recommends a basic maintenance regime. Because the grille is top-hung with sealed floor bearings, maintenance is minimal but essential.

• Track Cleaning: Regularly vacuum or sweep the recessed 25mm bottom U-channel to ensure the sill guide and steel bearings remain completely free of dirt, debris, and obstructions.
• Surface Cleaning: Wash the powder-coated steel framework with a non-abrasive, mild soap and water solution to remove environmental contaminants. Do not use harsh chemical solvents.
• Locking Mechanism: Ensure the keyways of the Winkhaus VS604 external cylinder and internal EMESC mechanism are kept clear of dust. Use a graphite powder lock lubricant periodically if required; never use wet oil-based lubricants inside the cylinder.

How to Measure for the Trellidor Trojan II T1000

Because the Trellidor Trojan II T1000 (Trojan S2 Pro) is a heavy-duty, LPCB Level 2 certified security grille, precision measurement is critical. The system must be securely anchored into solid structural substrates on all four sides. Providing accurate measurements ensures that the final product maintains its full Secured by Design rating and operates effortlessly.

Step 1: Understand the Substrate

Before measuring, verify that the structural opening where the grille will be installed consists of an approved solid substrate. The perimeter must be capable of holding heavy-duty M8 Tensile Grade 12.9 steel bolts. Approved materials include solid brickwork, reinforced concrete, concrete block-work, or structural steelwork. If your opening features decorative cladding, plasterboard, or timber, you must measure back to the solid structural material behind it.

Step 2: Measuring the Opening Width

Do not assume the opening is perfectly square. You must take three separate width measurements across the structural reveal.

1. Measure the width at the very top of the opening.
2. Measure the width across the exact middle of the opening.
3. Measure the width at the very bottom, at the Finished Floor Level (FFL).

Crucial Tip: Always record the smallest of the three width measurements. This guarantees the grille's fully framed system will physically fit inside the opening.

Step 3: Measuring the Opening Height

Similarly, you must measure the height in three different locations to account for any sloping in the floor or lintel.

1. Measure the height down the left-hand side of the opening.
2. Measure the height down the exact centre.
3. Measure the height down the right-hand side.

Crucial Tip: Again, use the shortest of the three height measurements as your final height dimension.

Step 4: Factoring in the Floor Track

The Trellidor Trojan II T1000 features a trip-free bottom channel that must be recessed beneath the floor surface. When measuring the height, ensure you are measuring from the top lintel all the way down to the Finished Floor Level (FFL). During installation, a 25mm deep trench must be cut into the floor to accommodate the galvanized U-channel.

Step 5: Stacking Space & Configuration Planning

When the grille is open, the steel flights stack tightly to one or both sides (depending on your chosen configuration). This stack takes up physical space within the opening.

• If maximising clear walk-through space is critical, consider measuring for a wider aperture or planning for wall cavities/recesses where the stacked grille can be hidden out of sight.
• If you are securing a span larger than standard doors, the system is available in multi-sash, double-leaf, and flexi configurations to accommodate virtually unlimited widths.
