The catalog was last updated on October 4, 2026. If a figure here and the one at checkout differ, the checkout is right.
What we update, and how often
We update prices, and which tints, shades and sizes are on offer, on a schedule, several times a month, from our own product data. A part that stops being offered leaves the site at the next update and comes back by itself when it returns. Prices on this site are the figures from our last update, not a promise.
What stays the same between updates
Part numbers, window sizes, shade numbers, noise reduction ratings and the standards a part is made to belong to that part, not to a price, so they change only when the part changes. We print each one only where it is published for that part: a window that does not name its material has no material line on its page, and a standard chip appears only where our product data for that part names that standard.
Ratings
Star ratings and their counts are the ones buyers gave each product family. Where one shield comes in several tints or one goggle in two lens coatings under one family, the family is counted once.
Sources
Our guides cite OSHA, NIOSH, ISEA, the American Academy of Ophthalmology and Prevent Blindness. We open and read each source before we quote it, and the date we read it is printed beside it. How we hold these figures to the Sellstrom product notes is written up in our editorial policy.
