Many precasters don't realize there are alternatives to fastening rebar with wire ties or welding. When it comes to joining rebar, most people think of wire or welds, but there’s another option: polycarbonate rebar clips. In many cases, rebar clips can be the better choice, offering strength, speed, and safety benefits that traditional methods can’t match.
The Kodi Klip Connecting System uses lightweight air tools to affix non-metallic, molded polycarbonate rebar clips (called Kodi Klips) to any cross, parallel, or vertical rebar joints, or rebar to strand. These clips provide a four-point rigid grip that guarantees a tight, perfect connection every time.
The Made in America (MIA) clips use recycled polycarbonate that won't crack, break, deform, rust or degrade, and they won't scratch or damage epoxy-coated rebar or fiberglass reinforcement either. Finally, each size is brightly colored to make them easy to distinguish and inspect. This system offers one of the fastest and safest ways of joining rebar without the need for wire or welding.
Typically, these non-metallic rebar clips are applied with a power tool. There is a cost for the tool, but it's significantly less than an automated tying tool. The price per connector is usually higher than a standard piece of tie wire but the application speed and added strength to the rebar structure quickly offset the costs of hand wire tying or automated tool wire tying. Non-metallic rebar fasteners allow the work to be done in the shortest time period and provide incredibly strong connections.
Q: How do you connect rebar without welding? A: Rebar clips are a great alternative to connecting rebar without welding or tying. Rebar clips can be a better option than more traditional methods like welding due to their strength, speed, and safety benefits.
Q: What are the main advantages of using KODI KLIP® Rebar Connectors over wire-tying rebar? A: KODI KLIPs significantly reduce installation time – by up to 80% – compared to hand-tying. They offer consistent, secure connections, reduce worker fatigue, and improve jobsite safety by eliminating wire scraps and repetitive wrist motion injuries.
Q: How do KODI KLIPs compare to welding for securing rebar intersections? A: KODI KLIPs are faster, safer, and easier to install than welding. They don’t require skilled labor, fire permits, or post-inspection for weld integrity, making them ideal for precast plants and job sites with tight schedules or safety constraints.
Q: Are KODI KLIPs strong enough to replace tie wire or welds in structural applications? A: Yes. Independent lab tests and field usage confirm that KODI KLIPs meet or exceed strength requirements for typical reinforcement assemblies, especially in precast and non-seismic work where speed and consistency are critical.
Q: Can KODI KLIPs be used in all types of rebar sizes and configurations? A: KODI offers Klips for a wide range of bar sizes and angles. They’re especially effective in repetitive setups like cages, mats, and grids found in precast concrete and flatwork. Specialized Klips accommodate multiple bar intersections.
Q: Do I need a special tool to install KODI KLIPs? A: Yes. KODI KLIPs are installed using a lightweight, battery-operated or pneumatic KODI gun, which drives the Klip securely in seconds with minimal effort – no twisting or welding required.
Q: How do KODI KLIPs affect jobsite safety? A: They eliminate exposed tie wire ends that can cause cuts and snags. Crews also avoid repetitive motion injuries and welding-related risks. KODI KLIPs promote a cleaner, safer work area.
Q: Are KODI KLIPs more expensive than tie wire? A: On a per-piece basis, yes – but labor savings, faster production, reduced injuries, and higher quality control usually result in a lower total installed cost compared to tying or welding.
Q: Where are KODI KLIPs most commonly used? A: They’re widely used in precast concrete manufacturing, tilt-up construction, foundation work, and highway/bridge decking – anywhere repetitive rebar connections are made and productivity matters. Q: Can KODI KLIPs be used in outdoor or harsh jobsite environments? A: Yes. KODI KLIPs are made from corrosion-resistant polycarbonate, making them suitable for use in both indoor and outdoor conditions. They hold up well in heat, cold, rain, mud, and dusty environments, and are designed for rugged jobsite use.
Q: Will using KODI KLIPs speed up overall project timelines? A: Absolutely. Faster rebar assembly means shorter forming and pouring cycles, allowing crews to move through projects more quickly. Precasters and contractors regularly see measurable productivity gains when switching from tying or welding to Klipping.
Q: Are there any training or learning curves involved in switching to KODI KLIPs? A: Minimal. Crews typically master the KODI KLIP gun in under an hour. Since the process is intuitive and ergonomic, precasters and contractors consistently see improved quality and fewer installation errors compared to hand-tying.
There are numerous and varied benefits to using non-metallic rebar fastener clips on most jobs. Eliminating hand tying reduces repetitive use injuries from the twisting motion. Increasing connection strength drastically reduces the chance of a pinch or collapse injury. Eliminating steel ties altogether reduces the number of cuts/scrapes/infections. And, if MIA issues matter on your job, problem solved!
