CUBIS manufacture all ULTIMA™ parts in GRP.

Glass Reinforced Polyester Resin (GRP) is an ideal material for access pit products due to its high mechanical and chemical properties, fire retardancy and the fact that it does not suffer from creep.

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.

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 cable pit sizes.


Fast and easy to install
STAKKAbox™ access pits are significantly faster to install than conventional alternatives, with complete installations typically taking up to one hour. This results in reduced costs for the installer.  Only the largest sizes in the range require specialist equipment or plant in order to install the access pit. 

Sectional & twin wall design
Pits are built to required depth by adding 150mm sections. Due to the twinwall design, individual sections are light meaning they can be manually lifted. Each access pit possesses vertical and horizontal ribs,  resulting in a product that is strong vertically and on the sidewall. For most applications, ULTIMA doesn’t require specialist backfills, reducing installation costs.

Smooth outer walls with lip to ‘key in’
Gaps in the outer wall will negatively impact the effectiveness of compaction around the access pit. STAKKAbox™ pits have smooth outer walls and an outer lip which keys into the backfill.

Variability in size
STAKKAbox™ ULTIMA can be used to create virtually any conceivable access pit clear opening. ULTIMA offers a huge range of pit dimensions thanks to the large number of standard sections and the variability offered by the ULTIMA Connect system.

Flat pack
STAKKAbox™ ULTIMA can be shipped ‘flat packed’ to reduce shipping costs. A large pit, as used on power stations or waste water treatment works, could be reduced to a number of pallets rather than occupying an entire truck.

Flexibility in Construction 
Duct entries can be quickly and safely formed on site. Overbuilding or benching is easily achieved. Fine top level adjustment is possible by horizontally cutting the top section.

Flat pack
ULTIMA access pits can be sent to site in ‘flat pack’ format, allowing for flexibility in delivery and installation.
