Two-Component Grout And Anchor Guns
Dual-component guns in 1:1, 2:1 and 1:4 ratios, up to 420 KG push force and 45:1 drive ratio
Structural Anchoring And Rebar Fixing
1:4 injection anchor adhesive guns for post-installed rebar and anchor bolts
Chemical anchoring is the one dispensing job where getting the ratio wrong is a structural failure rather than a finish defect. The JS8610 is built for 1:4 injection anchor adhesive specifically: two extrusion rods driven together, a welded frame and a thickened push rod, so the proportion holds under the force needed to push resin through a mixing nozzle.
Industry pain points
What Goes Wrong In This Trade
Ratio Drift On A Two-Part Anchor
If the resin and hardener do not leave the cartridge at 1:4, the anchor does not reach its rated bond strength, and nothing visible tells the installer. The JS8610 drives both rods from one linkage so the ratio is mechanical, not a matter of technique.
Force Through A Static Mixer
Anchor resin is stiff and the mixing nozzle adds resistance. A 30:1 drive ratio with 170 KG push force is what makes a full cartridge dispensable by hand overhead.
Frames Bending Under Load
The JS8610 frame is welded rather than assembled, with a full aluminium alloy handle and a thickened push rod, and carries a 200 KG tolerance against its 170 KG working figure.
Overhead And Awkward Positions
Anchoring often means working above shoulder height. The die-cast aluminium front handle uses a wave profile to keep the grip secure when the operator cannot see the gun.
What buyers need
What This Trade Actually Asks For
- A gun built for the specific 1:4 anchor ratio, not adapted to it
- Enough drive ratio to push resin through a mixer by hand
- A welded frame with published tolerance headroom
- A grip that works overhead and in awkward positions

Where Most Buyers In This Trade Start
How we work with you
From Enquiry To Repeat Order
Confirm The Cartridge And Ratio
Send the anchor resin cartridge specification. 1:4 is the JS8610; 1:1 and 2:1 products go to the JS8612 and JS8615 models.
Check The Nozzle Thread
Mixing nozzles vary by resin brand. We confirm thread compatibility before quoting rather than after delivery.
Sample On The Real Resin
Trigger effort with a mixer fitted is the only test that matters. Samples go out for exactly that.
Brand And Pack
Standard colour is orange; logo and carton design follow your specification. One piece per poly bag, 20 per carton.
Supply With Spares
Push rods and plungers are quoted alongside the order, since anchoring work is hard on both.

Guides For This Trade
How To Read Caulking Gun Force Ratings
Push force, maximum tolerance and drive ratio describe three different things. Confusing them is the most common reason a gun fails in the field.
Choosing A Two-Component Gun By Mix Ratio
The ratio is built into the gun's linkage, so a 1:1 gun cannot dispense a 1:4 product. Match the gun to the cartridge, every time.
A Private Label Caulking Gun Specification Checklist
Everything a factory needs from you before an own-brand run, in the order it gets asked, so the quotation comes back once rather than four times.
FAQ
Structural Anchoring And Rebar Fixing Questions
Which model is for injection anchor adhesive?
JS8610, purpose-built for 1:4 injection anchor adhesive at 170 KG push force, 200 KG tolerance and a 30:1 drive ratio. It uses two extrusion rods driven together so the ratio is held mechanically.
Can the JS8610 be used for 1:1 epoxy grout?
No. The rod geometry sets the ratio, so a 1:4 gun is not a 1:1 gun. For 1:1 use JS8612-A, JS8612-B, JS8615-2 or JS8615-3; for 2:1 use JS8615.
Will it push resin through a mixing nozzle overhead?
That is the design case. The 30:1 drive ratio keeps trigger effort manageable with a mixer fitted, and the wave-profile die-cast front handle is shaped for grip when you cannot see the tool.
Do you supply the mixing nozzles?
Nozzles can be packed with the gun as part of accessory customisation. Send us the resin brand and nozzle thread and we will confirm what we can supply.
Is the gun approved for use with a specific anchor system?
No approval by a resin manufacturer is documented on our materials. If your market or specification requires a system-approved dispenser, raise it before ordering so we can tell you honestly what we can and cannot support.
