Specifications

Compatibility and use

Confirm the flange bolt-hole diameter, flange thickness and required working clearance before purchase. The supplier describes the set for common ASME Class 150 flange fit-up, but compatibility depends on the actual flange dimensions. This is a positioning aid only; it is not a lifting, load-bearing or certified inspection device. Follow site procedures and remove the pins before final bolting or operating the line.

Dimensions are supplier-stated and may vary slightly between production batches. Matrico verifies the ordered model and performs a pre-dispatch visual check. For project quantities or application confirmation, use the single Request a Quote button on this page.
