[Tweet](https://twitter.com/share) (Tulsa, OK) Crosby is pleased to introduce two new capacities of McKissick 70 & 80 Series tubing blocks. The new tubing blocks are a better match for the increased mast capacities of today’s well servicing rigs. ![Tubing_Block_Banner_Ad_393x301](https://news.kitocrosby.com/hs-fs/hubfs/Tubing_Block_Banner_Ad_393x301.jpg?width=293&name=Tubing_Block_Banner_Ad_393x301.jpg) These new block capacities provide maximum flexibility to our customers and are setting the new standard in tubing blocks for the well servicing industry. The new 125 & 175 ton working load limit tubing blocks incorporate all the same features and benefits you expect from the leading block manufacturer, including being RFID equipped for electronic inspection tracking. All Crosby McKissick tubing blocks are manufactured to API 8C standards.  Additionally, McKissick tubing blocks incorporate a new lock arm design featuring a self-retaining bolt, and a new 35 Ton capacity rod hook clevis is available. Crosby McKissick continues to be a leader in the energy market with innovative designs and services.
