Keder rail clips: hooks, clothes-line eyelets and light-chain clips, 3 sizes

Small clips that slide into a free keder rail from its open end: 2 hooks, 2 eyelets for the clothes line and 4 clips for a light chain or cable Ø 4–8 mm per set. Three sizes.

Fits: Free keder (awning) rails without a keder in them, channel about 6, 7–8 or 10 mm; only for a clothes line, a light chain and light things. Not an accessory of any vehicle, furniture or awning manufacturer and not affiliated with one; no brand names, no logos on the parts.

Please note: nothing of this design has been printed yet, and it has not been tested in a vehicle. Some dimensions are estimates: board thicknesses vary, and keder rails have no published drawings (details under “Dimensions”). Load values are guide values: calculated, not tested in a vehicle. Print the free fit test with edge clamps S/M/L and keder test strips (in our “Magmacode” profile) first.

Is the keder rail free? Then it can carry a clothes line, a light chain and light things, without drilling or gluing.

• Only for a clothes line, a light chain and light things; not for an awning tent, an awning or storm guying.

• Slide in from the open end of the rail, the clip does not clamp the rail: only into a free rail with no keder in it.

• Before driving, take the line, the light chain and all clips out of the rail and stow them.

• Per set: 2 hooks (arm 16 mm, tip 8 mm), 2 eyelets (Ø 8 mm hole for the line), 4 open clips (Ø 9 mm bed, 8.5 mm opening) for a light chain or cable Ø 4–8 mm that is laid in.

• On the outside of the clip all edges are rounded R 3.2 mm, only the print bed side has a small chamfer; head and neck sit inside the rail.

In the set: small: head 5.5 / neck 2 mm; medium: head 6.5 / neck 3.5 mm; large: head 7.5 / neck 3 mm. Three files per size (hook, eyelet, clip); print 2 + 2 + 4 pieces.

Dimensions: Keder rails: drawings are not published. Retailer figures: keder bead 7.5 ± 0.3 mm, slot of the PVC rail 4 mm with a 6–8 mm channel; search snippets: 6 mm channel with 2.5 mm slot, 10 mm channel with 3.7 mm slot. Hence: small for a channel of about 6 mm, medium for 7–8 mm with a 4 mm slot, large for about 10 mm. The wall thickness at the opening is not documented: the neck is 3.2 mm long, lips of 1 to 3 mm fit, a thin lip with some play. The free keder test strips (in our “Magmacode” profile) show beforehand which size fits your rail. Calculated, not printed yet.

Load: Guide value 0.5 kg per clip, calculated, not tested in a vehicle. Safety factor against creep at 60 °C at least 2. Do not leave anything heavy on it while driving; stow loose items securely.

Material: PETG as the standard, ASA as an alternative. No PLA: a parked vehicle gets 60 to 70 °C inside in summer, PLA then softens.

For light items only, in the interior and on a free keder rail. No load securing, nothing load-bearing, nothing on gas, water, heating or electrical parts. Secure loose items safely while driving. The vehicle gets hot in summer: PETG or ASA, not PLA.

Variants (all included)

• Set small (head 5.5 / neck 2 mm)

• Set medium (head 6.5 / neck 3.5 mm)

• Set large (head 7.5 / neck 3 mm)

Print settings

• Material: PETG (or ASA). No PLA: a parked vehicle gets very hot inside in summer, and PLA then softens and deforms under load.

• Layer height 0.2 mm, 4 walls, 25 % infill, no supports.

• Orientation: Standing, as the files are laid out (rail direction vertical), no supports.

• Print time approx. 1 h 34 min and about 26 g (default set medium: 2 hooks + 2 eyelets + 4 clips; other sizes differ).

Assembly

1. Insert the clip at the open end of the free keder rail and slide it to the desired spot.

Safety

For light items only, in the interior and on a free keder rail. No load securing, nothing load-bearing, nothing on gas, water, heating or electrical parts. Secure loose items safely while driving. The vehicle gets hot in summer: PETG or ASA, not PLA. Do not leave anything heavy on it while driving; stow loose items securely.

Fit

If the clip slides too tight, take the next smaller size; if it slips through the slot, a size with a wider head. The test strips show this beforehand. Do not scale: head and neck would change together.

FAQ

Have you printed the part yet? Not yet. Calculated, not printed yet: dimensions, spring travel and loads are calculated, the part is not tested in a vehicle. Print the free fit test first and try it on your own board or rail. Which size fits my keder rail? Drawings of the rails are not published. The free keder test strips show beforehand which size fits your rail. The clip must slide in easily from the open end of the rail and must not slip out through the slot. Which material? PETG as the standard, ASA as an alternative. No PLA: a parked vehicle gets 60 to 70 °C inside in summer, PLA then softens.

How it's made

Parametric CAD (build123d, Python), exact solids. The CAD code was written with an AI assistant and checked by us; no AI-generated meshes or images. Renders are made from the CAD in Blender and show the part in simple staged scenes with placeholders (plain board, keder rail, towel, cup or phone without brand or logo); they are not photos.
