Universal ironwork frame levelling kit

ScrewLift™

ScrewLift is an adjustable frame levelling system, enabling micro adjustments to match ductile iron manhole covers and gully grating frames with their surrounds. It enables high-quality, consistent installations that resist early-life failure, extending the life of ironwork.

Simple but highly effective, ScrewLift provides a quick and repeatable method of levelling frames to the finished road surface while ensuring a minimum 15mm bedding depth. It’s ideal for both retrofit and factory-fitted applications, helping installers achieve accuracy and compliance across every site.

ScrewLift makes levelling ironwork simpler, quicker, and safer on site. By removing the need for manual lifting and micro-adjustments, ScrewLift helps to ensure installations are completed right first time, protecting both operators and the finished surface.

With standard levelling, each adjustment can mean minutes lost and repeated checks to reach the right height. ScrewLift removes that inefficiency. Its threaded lift system allows smooth, incremental adjustments with complete control. No need to lift, rebed, or re-check. In just a few turns, ironwork can be levelled to the surface, saving valuable time on every installation and keeping you on track.

Maintains a 15mm minimum bedding thickness beneath the flange, this ensures a minimum bedding thickness to maintain structural integrity and strength.
ScrewLift levelling screws can be adjusted from the top side of the frame using simple tools for accurate and fine alignment.
Achieve adjustments to match the surrounding road surface and camber in less time.
Simple to install with a firm push (or mallet) in the four insert points positioned near each frame corner, for even load distribution.
Prevents early life failure caused by poor bedding depth or frame movement.
Ensure a full and continuous bond between the frame and chamber, improve whole-life performance of ironwork installations.
Forms a key part of the Wrekin ironwork warranty.
Simplifies compliance with CD 534 and BS EN 124 installation guidance.

ScrewLift in Numbers: Efficiency You Can Measure

ScrewLift takes the strain out of installation by removing heavy lifting and multiple adjustments, delivering consistent precision and protecting both operators and surfaces. Explore the stats below to see the time and cost savings you can achieve.

reinstatement cost savings per installation.: Up to £5000
in savings on chamber repairs with ScrewLift.: Up to £15,000
bedding mortar depth guaranteed.: 15mm

Key benefits

ScrewLift provides specifiers, contractors, and asset owners with a consistent method for achieving long-term performance from every ironwork installation.

Consistent bedding depth

Guarantees a minimum 15 mm bedding layer for reliable, structurally sound installations. Prevents early-life failure and reinstatement costs of £1k–£5k per unit.

Accurate levelling and camber control

Can be adjusted by hand, hex key, drill or socket to match road camber. Prevents frame misalignment and impact damage, avoiding up to £15k in chamber repairs.

No makeshift packing

Removes the need for shims, debris, and other non-compliant materials, ensuring strong, consistent bedding.

Operator safety built in

Protects hands from being caught beneath heavy ironwork and reduces time spent exposed to traffic.

Precision without rework

Smooth, controlled screw adjustment means accurate levelling in seconds, no lifting, re-bedding, or micro-adjustments. Quicker, safer installations that stay on level and on schedule.

How does ScrewLift work

crewLift provides a precise mechanical interface between the chamber and frame, ensuring the correct height and orientation before bedding and surfacing.

Insert ScrewLift base units - For retrofit, insert each ScrewLift from the underside of the frame until it is firmly in place. Factory-fitted frames arrive with base units and levelling screws pre-installed.
Position the frame - Place the frame over the chamber using long-handled lifting keys. Ensure the flange is fully supported with no bridging or voids.
Level the frame - Adjust each levelling screw by hand, Allen key, socket or spanner until the frame sits flush with the surrounding surface.
Check alignment - Use a straight edge or string line to verify crossfall and camber. Fine-tune as required.
Bed and encapsulate - Apply UniPak bedding mortar (or suitable CD 534 compliant bedding mortar) to achieve a full, continuous bond between the frame and chamber. Pour flowable materials to the frame’s fill line indicator for complete encapsulation.
