Ultima Connect has been developed to offer greater flexibility in chamber sizes without compromising the strength of the standard Ultima system.
ULTIMA Connect features the same twinwall, sectional design as the standard system but sections are built from combining multiple parts. As with ULTIMA, all parts are manufactured in GRP.
The system comprises of corner pieces (‘hockey sticks’) and sidewall lengths. There are left and right handed corner pieces, which offers the ability to offset joints between sections in order to provide a brickwork effect. The corner pieces are referred to by the internal length on the long side.
These parts are connected using a jointing peg to form a variety of clear opening sizes.
Sidewall lengths can be used with the corner pieces to provide additional chamber sizes.
STAKKAbox™ is a range of sectional, modular and structural preformed access chambers. Access chambers are manufactured in various composite and polymer materials. Due to these features, STAKKAbox™ chambers are light in weight yet very strong, offering time saving benefits and a reduction in costs for the installer.
STAKKAbox™ sections stack on top of each other to offer flexibility in finished depth. Each ring section is castellated to positively interlock with the unit above and below.
The sectional design of chambers keeps the weight of each chamber part down, allowing for safe manual lifting.
Access chamber sections are available in ‘solid rings’ or as part of a system of modular component parts, offering huge choice in chamber clear opening.
STAKKAbox™ sections are twin walled to provide a strong yet lightweight product. Complete assembled chambers feature horizontal and vertical ribs for efficient transfer of loading.
STAKKAbox™ ULTIMA can be utilised for large chamber builds and are commonly used for applications such as power stations, waste water treatment works and sports stadiums.
STAKKAbox™ Ultima is commonly used for the following applications:
STAKKAbox™ Ultima is manufactured in Sheet Moulding Compound (SMC), a form of Glass Reinforced Polyester Resin (GRP).
Access chambers can be pre-fitted with the following accessories:

We extrude 100% recycled Low Density Polyethylene chamber bases to suit any chamber size. These are securely fitted to the bottom ring section of a chamber to provide a clean easy finish to the floor of the chamber. There is no requirement to 'float' a floor on site and the floor prevents vegetation and silt from entering.
Base section has a false floor with low-point for water to allow for drainage.
Meets the requirements of MCX 0815 for Motorway Communications.

Ultima Connect clear opening sizes are created by combining the corner pieces. This can include one or more sidewall pieces to offer a greater number of sizes.
The corner pieces are referred to by the internal length on the long side. This dimension will be 80mm shorter than the stated length as this is made up in the short length of the ‘corner piece’.
