Assembly

Required tools

Allen key SW 8
1

Remove the slot nut

We deliver the T-nut fully assembled, so the individual components are not damaged during transport. You also have a ready-made example for later installation. Disassemble the T-nut into its individual components and first gather the following:

  • the locking comb,
  • the centering cover,
  • 2 x M5 cylinder head screws, and
  • the SW4 Allen key.
2

Insert locking comb into floor rail

9 2

First, the locking comb is inserted into the vehicle's floor rail and held horizontally against the upper floor rail cover with the index finger and thumb of one hand. Make sure that the four locking lugs point toward the corresponding recesses in the floor rail.

3

Insert clamping block

10

The aluminum clamping block is then placed above the locking comb with its larger side facing upwards so that the holes are congruent with each other.

4

Fix the clamping block and screw it tight

11

Now, using your other hand and a 4 mm Allen key, insert the two M5 cylinder head screws into the two outer holes of the clamping block and screw them into the locking comb. If the threads don't engage immediately, move the locking comb slightly horizontally until the threads align. Tighten both screws by hand.

Note: These two screws will not have a load-bearing function later on; they only serve to center the locking comb.

5

Place cover plate

Einfach Montageplatte

Place the powder-coated cover plate onto the fixed slot nut.

6

Mount object

Now you can attach the items for which the floor adapter is intended to be used in the unused M8 threaded hole.

Note: Please ensure you use the correct screw length!

Usage

The correct screw length

The screw length used to attach the object should be determined using the following formula:

Screw length (measured without the head) = height of the object to be attached + minimum 22 mm / maximum 29 mm

Example

The object to be attached is 20 mm high; in this case, the length of the screw shaft (measured without the head) should be between 42 and 49 mm. Ideally, a washer should be placed under the screw head to prevent scratching the surface of the cover plate.

Safety instructions

  1. Please read these assembly instructions very carefully and completely to avoid errors when installing the floor rail adapter!
  2. The T-nut must be installed completely and correctly according to the enclosed or online assembly instructions.
  3. If the screw length is less than the specified minimum, there is a risk that the screw will not sufficiently penetrate the thread of the locking comb.
  4. If the screw exceeds the specified maximum length, there is a risk that the floor of the vehicle's floor rail will be dented and damaged.
  5. camptools is not liable under any circumstances for personal injury or property damage, or resulting financial loss due to improper installation or use of the product.
  6. Any modification, alteration, or misuse of the product is prohibited and will void any warranty or liability.
  7. Before installation, ensure that the seat rails are free of dirt, rust, or foreign matter and are in perfect working order.
  8. After inserting the T-nut, it must be manually checked to ensure it is securely seated in the rail.
  9. Depending on the type, size, and weight of the object to be fastened, multiple T-nuts must be used to ensure secure fastening.
  10. The T-nut is approved for vertical and horizontal loads only within the specified specifications. Excessive loading may lead to failure.
  11. The condition of the T-nuts and fasteners must be checked regularly – especially after transport or heavy use.
  12. Damaged, deformed, or worn parts must be replaced immediately. Continued use poses a safety risk.
