Frequently Asked Questions
Q: What is the difference between the CL 2777378 and CL 2777378-SG?
A: The CL 2777378-SG includes integrated string guard protection in addition to the standard caster wheel assembly. The string guard prevents rope, cord, and debris from wrapping around the wheel and axle during operation, reducing snag hazards in warehouse environments.
Q: What are the wheel specifications for the CL 2777378-SG?
A: The CL 2777378-SG features a 4-inch diameter by 2.5-inch width polyurethane wheel with a 2.047-inch bore. The wheel has a 95A Shore hardness durometer rating, providing superior wear resistance and floor grip for electric lift truck applications.
Q: What does the 95A Shore hardness rating mean for the CL 2777378-SG wheel?
A: The 95A Shore hardness rating indicates a moderately hard polyurethane compound. This hardness level provides excellent wear resistance and floor grip while maintaining reasonable flexibility and load-bearing capacity for typical warehouse pallet truck duty.
Q: Is the CL 2777378-SG string guard removable?
A: The string guard is an integrated component of the CL 2777378-SG assembly and is not designed for removal. If string guard protection is not required, the standard CL 2777378 without the guard is the appropriate choice.
Q: What is the bore diameter of the CL 2777378-SG and does it fit standard Clark axles?
A: The CL 2777378-SG has a 2.047-inch bore diameter. Verify this dimension matches your Clark axle specification. The bore diameter must align exactly with your equipment axle to ensure proper wheel fitment and load support.
