Key Features and Benefits
300mm Adjustment Range
With a 400mm threaded steel tube, this unit allows up to 300mm of height adjustment. You're able to compensate for ground variations without dismantling the structure, excellent for outdoor sites, sloped interiors, or temporary venues. Adjustments are simple, letting you get the stage level quickly so performers, kit, and crew can focus on the show, not the flooring.
4-Tonne Load Capacity
Each jack is rated for loads up to 4 tonnes. This gives you peace of mind for heavy stage builds, large risers, or supporting equipment-laden platforms. The high capacity also minimises flex, rattling, and the safety concerns that plague lighter products.
Custom-Sized, Zinc Plated Baseplate
Crafted for a snug fit with Stage Concepts deck legs, its 125mm x 125mm, 6mm-thick base is smaller than typical screw jacks. This means stage decks line up perfectly, yet stability and weight distribution aren't compromised. Zinc plating resists corrosion: key for outdoor use.
British Manufacturing,Certified Materials
Produced in the UK with steel complying to BS4360/43A, BS1139, and EN74. This assures dimensional accuracy, strength, and lasting reliability compared with many imports.
Applications
The stage leg extension screw jack is made for professionals in event production, theatre, festival management, and venue installation. Its precise adjustment allows you to create a perfectly level stage on challenging terrain, concrete car parks, grassy lawns, uneven gym floors, or old wooden halls. Touring productions find these invaluable where each venue offers new technical issues, and permanent installs benefit from the fine-tuning they provide during setup or reconfiguration.
Production companies, schools, village halls, and AV hire specialists all get repeatable height accuracy and on-site adaptability from these jacks. Their fit with Stage Concepts heavy-duty systems ensures reliability and quick handling where time and safety count most.
Summary
Designed for modern staging requirements, this stage leg extension screw jack is built with zinc plated, high-grade steel, a purpose-made compact base, and a 400mm threaded shaft delivering 300mm adjustment flexibility. It meets rigorous UK safety standards, supports heavy assemblies, and integrates directly with Stage Concepts' system. For professionals who build safe, configurable, and stable performance platforms in varying environments, it's a solid choice every time.
