Product Overview
The Calculated Industries #1190 Air Shim Inflatable Pry Bar is engineered for contractors and serious DIY enthusiasts who need a reliable, lightweight solution for precise alignment tasks. Constructed from a high‑strength fabric core encased in a durable rubber coating, the tool combines the flexibility of an inflatable wedge with the rigidity required to lift, pry, and level heavy components up to 300 lb. The non‑scuff cover ensures no marks are left on delicate surfaces, while the internal stiffener reinforces the wedge, preventing collapse under pressure. With a compact footprint of 10 × 7.5 × 1.5 inches and a weight of just 3.2 oz, it can be stored in a tool belt or a small toolbox, making it ideal for on‑site work and tight‑space applications.

Usage
This air shim excels in a variety of installation scenarios. Whether you are installing windows, aligning cabinet doors, or adjusting door frames, the tool’s ability to fit into gaps as narrow as 3/32 inches allows you to work where traditional wooden shims or metal pry bars cannot reach. The one‑handed squeeze pump provides smooth, incremental pressure adjustments, enabling a single installer to achieve perfect alignment without the need for additional crew members. The tool is also valuable for hobbyists working on furniture restoration, picture‑frame hanging, and any project that demands precise, repeatable positioning. Its hand‑held operation means you can use it in cramped attic spaces, under‑sinks, or on ladders without compromising safety.
