The Signature Keyless Frame allows artists to keep their linen canvases drum tight regardless of the humidity level and without loosening the squareness of the frame. With a single turn of a screw with a household screwdriver, wrinkles, puckers, and waves can be eliminated at any time during the life of a painting. Eliminate cumbersome keys that are difficult to use, and begin painting on Claessens linen on Signature Keyless Frames. The canvas will expand with precision and ease — and you'll once again experience the joy of painting on linen.

The stretched canvases are shipped assembled. However, they may need some tightening upon receipt depending on humidity levels. Directions for tightening the linen are included with each carton.

Respect for tradition and experience has made Claessens a household name with artists around the world. Craftsmanship and attention to detail are key elements in the manufacture of Claessens linen canvas, guaranteeing an archival support of exceptional quality that enhances the creative process.

Claessens linen is made entirely from natural materials that are grown, sorted, and processed with the greatest of care. Differences in the color, composition, and texture of these natural materials may occasionally lead to slight variations in the finished canvas. From an artistic and creative point of view, such variations are generally considered positive.

Canvases feature a traditional 1" profile. The 30" × 40" size has a cross brace for added support.
