NBframe is an innovative aluminium stretcher bar system for professional artists, museums and restorers. Its patented design creates a perfect framework for canvas stretching, free from deformation, twist and warp caused by humidity or dryness.
The inner aluminium structure is made of premium grade aluminium and provides for optimal structural integrity and stability. The FSC certified outer wood profile is shaped to smoothly guide the canvas along the flexible edge and allow for easy back stapling of the canvas. The flexible outer wall absorbs excess tension and ensures evenly and consistently stretched canvas.
