WHAT ARE REBAR GRIPS?
Rebar grips are mechanical wedge anchoring devices that transfer tensile force from a hydraulic jack into a reinforcing bar. Hardened, serrated wedges sit in a tapered steel body, so as the jack pulls, the wedges bite harder into the bar. Used with center-hole jacks, quick-acting rebar grips simply slide over grouted or epoxied rebar, allowing pullout tests to be set up in seconds on highway, bridge and tunnel projects. Grips are also available for rigging and special applications.

REBAR GRIP SPECIFICATIONS
📘 What Are Rebar Grips?
Rebar grips are wedge chucks that hold a reinforcing bar while a hollow hydraulic jack pulls on it. The load path is jack, grip body, wedges, then rebar.
The tapered body converts the axial pull into radial clamping force, so the harder the jack pulls, the tighter the wedges grip.
Grips are bar-size specific and are rated by their maximum tensile load, which must exceed the target test load by a safety margin.
⭐ Key Features & Benefits of Rebar Grips
WB Equipment rebar grips are designed for fast, reliable testing.
Hardened wedges
Serrated teeth bite into rebar ribs to prevent slip.
Precision taper
Typical 6° to 9° included angle for holding force and easy release.
Retaining spring
Holds wedges in position during setup.
Bar-matched sizes
Grips for #4 through #18 rebar.
High capacity
Used with jack systems up to 1,500 tons.
Rental or sale
Available to rent or buy, alone or with jacks.
🔧 Equipment Used with Rebar Grips
A rebar pullout setup typically includes:
• Rebar grip sized to the bar
• Center-hole (hollow plunger) hydraulic cylinder
• Hand, electric or battery hydraulic pump
• Calibrated gauge or load cell with readout
• Bearing plate or reaction chair
• Dial indicator for bar displacement
• Hoses and couplers
🏗️ Common Applications for Rebar Grips
Rebar grips are commonly used for:
• Pullout testing of grouted or epoxied rebar
• Highway and bridge dowel testing
• Tunnel and retaining wall anchor bars
• Proof loading post-installed rebar
• Tensioning reinforcing bars
• Rigging and special lifting applications
• Quality control on DOT projects
📈 Advantages of Rebar Grips
Compared with threaded couplers and welded fixtures, rebar grips offer:
Fast setup
No threading or welding of the bar.
Reusable
Grips and wedges can be used again and again.
Accurate testing
Axial load applied straight along the bar.
Minimal bar damage
Wedges grip ribs without cutting the bar.
Versatile
One jack can test many bar sizes with different grips.
⚠️ Limitations to Plan For
For safe, accurate rebar grip use, plan for:
• Using the correct grip for each bar size
• Grip capacity at least 25% above the test load
• Clean wedges and correct orientation
• Normal wedge seating slip at first loading
• Epoxy-coated bar needs special wedges
• Enough exposed bar length for the jack and grip
• Keeping people clear of the bar line during loading

Buying or Renting Rebar Grips
WB Equipment supplies quick-acting rebar grips for bar sizes #4 to #18, for sale or rental, together with the center-hole jacks, pumps, chairs and calibrated gauges needed to use them. Grips are matched to the bar size and jack, and the hardened wedges can be replaced as they wear, so a grip lasts for many tests.
For projects with a set number of tests, we can also supply a complete pullout test kit, ready to use.
Where Are Rebar Grips Used?
Rebar grips connect a jack to a reinforcing bar without threading or welding, which makes them useful for:
● Pullout tests: proving grouted and epoxied dowels on highways, bridges and tunnels.
● Post-installed reinforcement: checking new bars added to existing concrete.
● Anchor testing: gripping unthreaded bars and anchors for proof loading.
● Tensioning: applying load to bars during construction.
● Rigging and special uses: temporary connections to bar for lifting or pulling.
Because the grips slide straight over the bar, each test takes only minutes to set up.
Your Questions Answered - Rebar Grips
What are rebar grips used for?
Rebar grips hold a reinforcing bar while a center-hole jack pulls on it, mainly for pullout testing of grouted or epoxied rebar.
How do rebar grips work?
Wedges sit in a tapered body. As the jack pulls, the wedges are drawn deeper into the taper and clamp the bar tighter.
What rebar sizes do you have grips for?
WB Equipment supplies grips for #4 through #18 rebar.
Can one grip fit all bar sizes?
No. Grips are bar-size specific, so you need the correct grip for each bar diameter.
What jack is used with rebar grips?
A center-hole (hollow plunger) hydraulic cylinder, such as Enerpac or Simplex, with a hand or powered pump.
How much load can a rebar grip hold?
It depends on bar size. Typical capacities are 20 to 30 tons for #6 bar, 30 to 50 tons for #8 bar and 75 tons or more for #11 bar.
Why does the bar slip slightly at the start?
Initial wedge seating slip is normal and should be allowed for in stroke and displacement measurements.
Can grips be used on epoxy-coated rebar?
Yes, but epoxy-coated bar requires special wedges for reliable grip.
Do grips damage the rebar?
The serrations are designed to bite into the ribs and minimize damage while preventing slip.
How long do wedges last?
Wedges are durable but wear over time. Replace them when teeth are worn or damaged.
Can I rent rebar grips?
Yes. Grips are available for rent or sale, alone or with a matching jack and pump.
Are grips available for other uses?
Yes. Grips are also available for rigging and special applications.
