Screwjacks & Castors

What Are Screw Jacks?

Screw jacks, also referred to as leveling jacks or base jacks, are adjustable steel rods used at the base of scaffolding structures. They are designed to:

• Level scaffolding on sloped or uneven terrain
• Provide adjustable height to ensure plumb alignment
• Securely bear vertical loads transferred from scaffold frames or standards

Their robust threaded design allows for millimeter-precise adjustments, which is vital for aligning scaffolding on construction sites or in industrial environments.

Types of Scaffold Screw Jacks Available

At North Scaffold, we offer a complete range of scaffold screw jacks for sale to meet the technical requirements of various job sites and industries. Our products are fabricated using high-grade steel and manufactured to meet Canadian and international safety standards.

Standard Base Screw Jacks

• Designed for use with both frame and ringlock scaffolding systems
• Heavy-duty threaded shaft with forged base plates
• Available in multiple lengths (18″, 24″, 30″)

Swivel Base Screw Jacks

• Ideal for sloped surfaces or angular positioning
• Swivel plate pivots to accommodate surface gradients
• Galvanized finish for corrosion resistance

U-Head Screw Jacks

• Used to support horizontal components like aluminum stringers or beams
• Common in shoring and formwork applications

Caster Jacks with Wheels

• Combine mobility and leveling in rolling scaffold systems
• Locking mechanisms ensure safe positioning
• Designed for interior fit-out and light-duty applications

All our scaffold screw jacks are tested to ensure structural integrity under heavy loading and extreme weather – key for projects across Alberta and BC where climate conditions can vary drastically.

Why Quality Screw Jacks Matter on the Job Site?

Investing in high-performance screw jacks goes far beyond code compliance – it directly impacts safety, efficiency, and cost control. Inferior or poorly maintained jacks can cause scaffolding to shift, lean, or collapse, putting workers and project timelines at risk.

Here’s why contractors and engineers across Canada rely on North Scaffold’s screw jacks for sale:

• Load-bearing reliability to safely support multi-tier scaffolding systems
• Thread precision that maintains alignment under stress
• Corrosion resistance for durability in rain, snow, and coastal areas
• CSA-compliant manufacturing for peace of mind in regulated environments

Where to Use Scaffold Screw Jacks?

Our scaffold screw jacks are essential for a wide range of job types and industries, including:

• Commercial construction (mid-rise & high-rise buildings)
• Industrial facility maintenance (plants, refineries, utility sites)
• Infrastructure projects (bridges, overpasses, transit)
• Residential new builds and renovations
• Temporary stages and public event structures

Whether you’re building on uneven rock, compacted soil, poured concrete, or finished flooring, screw jacks ensure your scaffolding stays level and stable from day one to project completion.

Choosing the Right Screw Jack: Key Considerations

Not all jacks are created equal. Choosing the proper screw jack for your scaffold system depends on:

• Load capacity requirements
• Type of scaffold system (frame, ringlock, tube & clamp)
• Surface type (flat vs. uneven)
• Height adjustment range
• Required accessories (base plates, casters, etc.)
