About Specialty
3 Generations of Craftsmanship and Service
Our founder, Albert Knabb, was an engineer who built a culture of craftsmanship — people who take responsibility for their work.
His standard still guides us today:
Make it right, support the customer, and stand behind every order.
Nearly six decades later, we remain true to the same principles: consistent quality, honest lead times, and being ready to pick up the phone when you call.
It’s how we’ve earned trust and steady business since 1967.
When our customers succeed, we know we've done our job.

Proudly Local, Proudly American
From our facility in Reading, Pennsylvania, we’re proud to keep manufacturing close to home. Our trucks deliver across the Tri-State Area every day, supporting contractors, distributors and communities with products built to last.

A Family Business, A Dedicated Team
Behind every order is not just our family, but a skilled team of craftsmen, operators, and service staff who care about doing things right. Many of our employees have been with us for decades, and their pride in the work shows in every shipment.
Trusted by Contractors. Loved by Homeowners.
