Roof Bars for Cars Without Rails — Page 30
A smooth-roof roof rack is a pair of aluminum crossbars for cars without roof rails and without factory mounting points: the feet clamp onto the roof edge inside the door openings, so there’s no need to drill the roof or modify the body. This section offers two options — Erkul Asaf V4 (Turkey, 135 cm crossbars, for roofs up to 135 cm wide) and Niken Oluksuz V4; both are chrome and sold as a pair with a mounting kit.
What’s the difference between Erkul Asaf V4 and Niken Oluksuz V4
| Parameter | Erkul Asaf V4 | Niken Oluksuz V4 |
|---|---|---|
| Mounting | for smooth roof, clamps in the door openings | for smooth roof, clamps in the door openings |
| Crossbars | aluminum profile 135 × 7.5 × 3 cm | aluminum + plastic, profile length not specified on the product page |

Each of the two kits is shown on pages for hundreds of models — from Daewoo Lanos and Renault Logan to BMW 6 Series G32. It’s the same item with a single part number; the model page means the kit was selected specifically for that car. That’s why it’s easier to start with the filter: choose the make and model, and the list will show only the options verified for your body style. Erkul product pages include an installation manual you can download.
How to tell if you need a smooth-roof roof rack
First, look at your roof. The mounting depends on the roof type, and crossbars from a different system won’t fit a smooth roof:
- Roof rails with a gap above the roof — you need a roof rack for standard roof rails.
- Roof rails sitting flush on the roof (no gap) — a roof rack for integrated roof rails.
- Factory mounting points, often hidden under plastic covers or moldings — a roof rack for factory mounting points.
- None of the above — this page is your option.
If you want longitudinal bars along the roof, not just crossbars, see roof rails.
How to choose by roof size
Measure the roof width above the front and above the rear doors — exactly where the feet will sit. For Erkul Asaf V4, the width must not exceed 135 cm. Also double-check three cases: panoramic roof (where the feet will sit and whether the sunroof will open), coupe and 3-door bodies (whether the rear crossbar will fit), and vehicles with an unusual door opening shape. Send the manager roof photos and your measurements — they’ll match them to the kit.
What you can carry on crossbars
Crossbars are the base for cargo and accessories: roof boxes and cargo boxes, bike carriers, ski carriers. Before buying an accessory, check that its mounting matches the crossbar profile. The allowable load is determined by the lower of the two limits — your car’s roof load rating (listed in the owner’s manual) and the crossbars’ rating; distribute the load, including the box, evenly.
After installation, the doors close as usual, and the rack can be removed without marks on the roof — nothing is screwed into the roof. After the first few kilometers with a load, recheck the clamp tightness and how the door seal sits.
