1. Quick-Lock® Spacers: Fast, Strong and reliable
Manually tying or bolting together spacer wheels can slow crews and cause project delays. Instead, our Quick-Lock wheel spacers and boots provide:
- Tool-free installation in seconds, reducing crew time and labor.
- Noncorrosive, durable polymer construction that holds up to rigorous jobsite handling and pour pressures.
- Consistent or uniform concrete cover to meet design and code requirements.
Explore the options:
- Quick-Lock Pier Wheel: Positions reinforcing cages in drilled shafts while maintaining cover.
- Quick-Lock HD® Pier Wheel: duty version for larger or more demanding applications.
- Quick-Lock Pier Boot®: Supports cages off the drilled shaft base, improving vertical alignment and cover consistency.

2. Adjustablility: Our Solution for Your Conditions
Onsite conditions often deviate from what the designer originally planned back in the office — shaft diameter, cover requirements and reinforcement sizes change. Adjustable centralizers meet these challenges, through:
- Wide-range compatibility to fit varying reinforcement sizes and shaft dimensions.
- Rapid installation, with two identical halves that snap together and are securely held in place with tie wire.
- Uniform positioning during concrete and grout placement to meet design requirements.
Relevant products:
- Quick-Lock Unibar® Centralizer: Keeps threaded rods, rebar or tendons centered in boreholes for consistent cover.
- Adjustable Quick-Lock Unibar Centralizer: Adjustable centralizer maintains performance reliability while accommodating a wide range of bore hole and shaft diameters to meet project requirements.

3. Stabilized Cages During Placement to Preserve Cover
Even with proper staging, cages can shift during high-volume pours, leading to insufficient cover and inspection failure. Effective alignment tools:
- Resist lateral movement from concrete flow or vibration.
- Ensure cages remain centered from lowering through final concrete set.
- Help crews avoid rework, pass inspections consistently and reduce downstream risk.
These products aren’t just about convenience — they support quality control, inspection readiness and structural integrity.
