Ripplefold Snap Tape creates the gently flowing waves of a Ripplefold drapery. The spacing between the snaps on the tape is always 4 1/4". It's the spacing between the Ripplefold Carriers that determines the fullness, not the Snap Tape.
As you can see, regardless of your master carrier style, the snaps on the master probably aren't going to be 4 1/4" apart, so you'll have to do some alterations to your Snap Tape. It's really a good idea to have your rod on-site before the Snap Tape is sewn into the header of your drapery.
Combo Drapery Rods are a specialty hybrid rod that include both a stationary drapery pole and either a Decorative Traverse Rod or Heavy-Duty Curtain Rod. Combo Curtain Rods can be made with full-length front poles or with smaller poles for stationary side panels.
You can see the cam assembly right below the mounting arm of the Combo Bracket. There is absolutely no difference between mounting a Combo Rod and any other Decorative Traverse or Heavy-Duty Rod previously mentioned.
