The Sagitta was perfect for steel fences. I used a few. I even used neodymium magnets to attach some to a solid wrought iron fence (not hollow steel square tubing) on one job.
Never used a Soffitliter.
I used some cast brass Integraliters on a job where there was a basketball hoop on the driveway and stray shots bounced off the ground level fixtures with no damage.
