Columbia Inside 90 Corner Applicator

The Columbia Inside 90 Applicator Head (IA90) is a professional-grade tool for applying joint compound to 90-degree inside corners before taping. It ensures a consistent and even distribution of mud, which accelerates the pre-filling process. This applicator head is compatible with standard corner applicators, such as compound tubes and corner boxes.

Consistent and Controlled Mud Application

The IA90 features proportionate, channeled grooves that provide a controlled and evenly dispersed flow of mud. This design allows for the simultaneous application of compound to both sides of an internal corner, preparing the surface for tape application.

Durable and Lightweight Construction

This applicator head is machined in Canada from Ultra-High Molecular Weight (UHMW) polyethylene. This material is known for its exceptional durability, strength, and resistance to abrasion and wear, while also being lightweight.
