Herculock specializes in securing two pieces of metal together in the repair of cracked or broken metal castings. This procedure is known as metal locking. The repairs can be done in our shop or on-site. The process has no heat applied and the result is no distortion or shrinking of the fully repaired metal casting. Herculock of Niagara Falls has provided a guaranteed service in Canada and the United States since 1944. Owing to the nature of our service, most clients have only an occasional requirement, thus, we have acquired a great number of diverse customers from a wide area.
