Are рейлінги and crossbars the same thing?

No. рейлінги are two longitudinal rails along the roof, while crossbars are mounted across the рейлінги, and the box or other cargo is then attached to them. Crossbars for рейлінги are usually purchased separately.

Do I need to drill the roof to install рейлінги?

Not always. Model-specific рейлінги are installed in factory mounting points or with glass adhesive sealant without drilling. Drilling may only be needed for universal рейлінги if you choose a roof-screwed mounting option; the installation method is specified in the characteristics.

How do I choose universal рейлінги?

Measure the roof length and the distance between the points where the feet will be placed, and compare them with the dimensions in the product specifications. Universal рейлінги may require adjustment to fit a specific roof.

What weight can рейлінги support?

The permissible load is determined by the lowest limit of the system — the roof, рейлінги, crossbars, and mounts. Take into account the weight of the box itself and distribute the load evenly.

What crossbars are needed for integrated рейлінги?

For integrated рейлінги without a gap above the roof, you need crossbars with mounting designed specifically for this profile. Clamps for raised рейлінги will not fit them.

Does "chrome" in the name mean chrome-plated steel?

No, the color in the name describes the appearance. The material of the profile and feet is specified in the characteristics: most often it is aluminum or aluminum with plastic.
