Comparing a Panel-Hole Insert with a Covered Gland Housing
I drilled roof boxes and fitted glands and threaded adapters.
The cable routes came together around those separate entries.
My purchased entry supplies also included rubber panel grommets in several sizes.

My Takeaway from This Job
The grommet surrounds a panel hole, while a covered gland housing groups a different set of entry components. BUSY-CORNER and Cal-Hawk offer individual rubber inserts; Link Solar supplies a complete two-gland cover.
A rubber panel insert and a complete gland housing are different entry formats.

Assortment
Multiple opening sizes
A grommet sits in the edge of a panel hole, while its center opening surrounds the cable or bundle. Those are two different fit measurements. For a van cable entry, record the panel opening and thickness alongside the finished cable diameter. Check the assembled shape rather than choosing only by the largest measurement in the assortment. My purchased grommets remain separate from the roof-box glands in the diary, since a grooved grommet and a threaded gland use different mounting arrangements.
The panel-hole size and panel thickness describe the outside fit. The center opening describes the cable space.

Two Alternatives to Compare
The Cal-Hawk assortment offers another set of individual rubber grommets, while Link Solar uses a complete two-gland entry housing; these are different approaches to the surrounding panel opening.
