The Square Bell Lamp Shade exemplifies enduring style with its timeless silhoutte - a simple, square shape with a slightly flared bottom. This shade works best with lamps with a narrow base, making it the perfect choice for buffet lamps. With a variety of fabrics and color options, it is versatile enough for use in traditional, transitional and modern homes. The Square Bell Lamp Shade is part of the Royal Designs, Inc. Timeless Basic Shade Collection. Royal Designs has been in the lamp shade business since 1993 with our multiple shade lines that exemplify handcrafted quality and value. Height is measured by slant height from top to bottom of the lampshades’ front face. Measurements listed as (TOP x BOTTOM x HEIGHT). Please measure your existing shade--a replacement harp may be needed for a proper fit or additional adjustment if changing height of shade.
