The BON TOOL 51-145 is a wave-profile comfort grip replacement handle designed for brick trowels used in masonry and tile work. The contoured wave shape reduces hand fatigue during extended use, making it a practical swap for worn or damaged handles on existing trowels. Constructed from a durable plastic blend, this handle measures 5.98 inches in length with a 1.26-inch diameter profile and weighs 2 pounds. It is suited for journeymen masons, tile setters, and masonry contractors who spend long hours on the trowel and need a handle that holds up to job-site conditions.
This replacement handle fits both carbon steel and forged steel brick trowels, making it a versatile option across a range of trowel types commonly found on residential and commercial masonry jobsites. It is typically installed when an existing handle cracks, loosens, or causes discomfort during prolonged use. The wave grip design distributes grip pressure more evenly across the palm, reducing strain during repetitive trowel strokes.
Fits both carbon steel and forged steel BON trowels. Designed as an OEM-style replacement handle for BON brick trowels requiring a comfort grip upgrade or handle swap.
Handle replacement on masonry trowels is typically performed by masons or tile setters using standard hand tools. Remove the existing handle by loosening or driving out the fastening hardware before seating the replacement. Ensure the blade tang is fully seated and secured in the new handle before returning the trowel to service. Do not use a trowel with a loose or improperly seated handle.
