Door Closers| Cal-Royal

The Cal Royal Products 300 Series Door Closer comes in two versions.   One version is the size 3 to 6 spring, which would be for larger exterior doors.  The 3 to 6 spring size is for doors 36" to 48" wide.  The second version is the size 1 to 4 spring size.  The 1 to 4 is considered a Barrier Free door closer, because the spring tension can be turned down to less than 8 pounds of resistance, making the door easy to open.  The 1 to 4 should be used on interior doors and smaller, less than 36" wide exterior doors.  This door closer is a standard template closer with a hole spacing of 3/4" x 9-1/16" center to center, which is what we find on many aluminum framed glass storefront doors.   This closer has a 5 year warranty and is considered a Grade 1 closer, the heaviest duty rating possible.

The Cal Royal Products 400 Series Door Closer is for lighter use interior doors.  This closer is considered a Grade 2, which means it is only rated for 1,000,000 cycles.  The 400 Series is a sized closer, meaning you can not adjust the spring tension, the spring size you select is what you get.  Also, make sure to note the hole spacing of the various sizes below.  These closers also offer adjustable closing and latching speeds.

Size 420 3/4" x 6-5/8" hole spacing

Size 430P 3/4" x 8-3/16" hole spacing
