The Model 250 is a larger redesigned version of our popular ball-bearing sash pulley. It has been designed to meet the needs of custom high-end window fabricators building large and heavy sash, and enables the use of 2" diameter or 2" square counterweights in most applications. The Model 250 features a solid brass 1 1/8" x 5 7/16" radius end faceplate, 2 1/2" solid brass precision turned pulley wheel for chain or cord, and a sealed ball-bearing for many years of smooth operation. The standard finish is satin lacquered brass; other finishes are pictured below. Use the pull down menus to select the desired finish. The Model 250 is designed for use with up to #45 sash chain or #10 cord. Faceplate dimensions: 1 1/8" x 5 7/16". Housing dimensions: 2 3/16" x 3 1/4" x 3/4". Center of chain or rope will be 2-3/16" back from face of window jamb. For 1" thick window jamb, this will allow pockets to accomodate up to 2" diameter sash weights. 250 Satin BrassRegular price: $30.34Sale price: $26.25, 4/$97.00, 12/$249.48, 100/$1,964.00 Finish: Satin Brass Lacquered 2-1/2" Sash Pulley Custom Finish 250 Custom FinishRegular price: $39.44Sale price: $33.60, 4/$120.00, 12/$318.84, 100/$2,541.00 Finish: Polished Brass LacqueredOil-Rubbed BronzePolished Brass UnlacqueredSatin Nickel 2-1/2" Sash Pulley in Polished Nickel 250 Polished NickelRegular price: $45.52Sale price: $37.80, 4/$138.60, 12/$369.72, 100/$2,888.00 Finish: Polished Nickel -Finishes shown from left to right: Oil-Rubbed Bronze, Polished Brass, Satin Brass, Polished Nickel, and Satin Nickel.
