Stronglite Composite Lid P5 – Class B with Barri Bolt Holes (Lockable)

• Two Barri Bolt holes in diagonally opposite corners, so you can retrofit locking to existing P5 plastic pits
• Australian designed and made, so we turn around custom colours, markings and engraving quickly
• Class B load rating to AS 3996-2019 for cars and light vehicles at slow speed, such as driveways, but not for trucks
• 9 kg, so it’s under a third of the weight of concrete and also lighter than many other composite P5 lids
• Meets the impact resistance requirements of AS 3996-2019, so the fibreglass-reinforced polyurethane resists chipping and cracking
• Slip resistance class P5 under AS 4586, which is the highest wet pendulum class, so the surface keeps its grip when wet
• Weather and UV resistant
• Adjustable dimple screws take up minor variation in pit openings and also help hold the lid in place during flooding
• Approved by SA Power Networks

This lid covers underground P5 plastic pits where light vehicles may cross, such as driveways, footpaths open to vehicles, verges and livestock areas. Choose the lockable P5 composite lid when you need to stop unauthorised access to cables, conduit or equipment, especially in public areas.

SA Power Networks has approved the Stronglite P5 Class B lid. We also supply the Stronglite range to Metro Trains. In addition, selected VicRoads and Department of Transport and Planning (DTP) project drawings specify Stronglite lids.

Working on a VicTrack project? VicTrack requires Class C, so choose the Stronglite P5 Class C Lockable instead. VicTrack has approved the Class C lid, and the VicTrack Comms marking is only available in Class C.

Compared with other composite lids, Stronglite stands out in a few practical ways:

• Retrofit locking: the lock kit fixes into the corners of the pit you already have, so you can add locking to existing P5 plastic pits. In contrast, some locking systems are built around their own pit range.
• Fits varying pits: the lid fits P5 plastic pits, and adjustable dimple screws also take up minor variation in pit openings.
• Lighter to lift: 9 kg, whereas many composite P5 lids weigh up to around 20 kg.
• Made locally, made to order: Australian production means quick turnaround on custom colours, markings and engraving.
• Proven performance: Class B and impact resistance to AS 3996-2019, plus slip resistance class P5 under AS 4586.

Against concrete, the gap is even wider. Concrete lids cost less up front, but they can crack and chip over time and eventually need replacing. Our concrete P5 lid also weighs 31 kg, is only Class A and has no locking option. Stronglite costs more initially; however, it stays in service longer, locks to the pit and is far easier on the people who lift it.

Overall, the Stronglite lockable P5 composite lid is the premium choice where the pit needs locking, light vehicles may cross, or you need a custom finish.

For standard orders, choose from 11 markings: Plain, ARTC, Comms, Electrical, Rail Sign Comms, V/Line, VERNet, VicRoads Comms, VicRoads Electrical, Vocus and Water. Grey is standard on every marking. In addition, bitumen black is standard on Comms and Electrical, so those lids blend in with asphalt and bitumen surfaces.

The marking only shows which network or authority owns the lid on site. However, it doesn’t change the material, dimensions or load rating, because those stay the same across every option. Check your project specification for the correct marking and colour before ordering.

Need something outside the standard range? Australian production means a shorter supply chain and quick turnaround. Because of this, your lids can match your project’s requirements instead of whatever happens to be on the shelf.

For example, we can supply Stronglite lids with:

• Custom colours, such as a match for the surrounding surface, a council palette or a network standard
• Custom markings for authority, network or asset-owner identification
• Engraved text or logos, for example company, council or project branding

Minimum order quantities apply to custom lids, so contact us early to discuss your project.

This product is the lid only. To lock it, you’ll also need a Stronglite lock kit, plugs and a 28 mm Barri Bolt key, which we sell separately. Each lock kit covers one pit and includes:

• 2 lock plates, each with an M12 nut welded on
• 6 x 10G SS316 self-tapping screws, so 3 per plate
• 2 x M12 Barri Bolts

In addition, you’ll need Barri Bolt plugs and lifting hole plugs, which come in black or grey.

For installation, you’ll also need a cordless drill, a PH2 driver bit, the 28 mm Barri Bolt key and suitable PPE. Then follow these steps:

1. Sit both plates loose in diagonally opposite corners of the pit, but don’t fix them yet.
2. Place the lid on, then drop a screwdriver through each bolt hole and slide the plate to line up with the nut.
3. Lift the lid off without moving the plates, then fix the first plate into the corner of the pit.
4. Refit the lid to check the second plate hasn’t moved. Then lift it off again and fix the second plate flat and even.
5. Place the lid back on, check the holes line up, then screw in both Barri Bolts with the key. However, don’t overtighten them.
6. Finally, fit Barri Bolt plugs over the bolts and plug any unused lifting holes.

Because the lock plates fix into the corners of the pit, this works on new pits and on pits already in the ground. Once finished, the lid should sit flush with no rock or rattle. For a printable version, download the Stronglite Lock Installation Guide.
