What Are Your Crews Digging?
Tell us, and we’ll build a TrenchJack™ that covers it
TrenchJack™ is modular. Pick the size, add what the job needs.
The body is aluminum — moved by two people, no machinery. The cylinder is Triple Seal, pressure stays where you put it. The piston rod adjusts 20 inches inside its size range.
FEATURES
- Big Block Standoff, dirt clears
- Safety Finger Guards, no pinch points
- Certified Hydraulic Power
- Subpart P tab data with every kit
Everything the trench actually needs. Nothing it doesn’t.
Two trench jacks 34-56″ wide. Two 4×8 euro panels. Steel pump, fluid, release tool, removal hook. The way KUNDEL ships it most often. Not a recommendation — what crews actually order.
FEATURES
- Sales-verified configuration
- Stock available, ships in days
- Quote response in one business day
- Free customer support, direct line
Three Reasons KUNDEL Holds Up
Trusted by plumbers, contractors, and municipalities
We rebuild every kit. Compliance stays valid for life
The Certified Repair Program brings every cylinder back to our factory in Vienna. We strip it by hand, replace the seals, and test every rebuild at 300% load. We document the work and back it with a satisfaction guarantee. Your Subpart P Option 2 tab data stays valid for the years the kit works for you, not just the warranty period.
Four engineered features. Each one has earned its name
The Triple Seal cylinder is sealed three times so pressure stays where you put it under load. The Big Block Standoff is sized so dirt clears the connection instead of binding it. The Safety Finger Guards are oversized so the spreader block won’t catch your hand. The 20-inch piston rod fits more trenches per kit than a fixed-stroke setup.
A kit that keeps showing up to the work, season after season
The work changes. The crew rotates. The trenches shift. The kit stays. We build for repeat field use, and the Certified Repair Program keeps each cylinder field-deployable as the seasons roll over. That’s why the kit you bought stays the kit you use — through the work that comes next, and the work after that.
