The fixing point decides harness quality
In under-hood wiring work, the fixing point decides whether a harness stays tidy for the life of the vehicle. Heat cycling, vibration, oil mist and service access all act on the mount before they act on the tie, so specifying engine bay harness cable tie mounts is a panel-first decision, not a tie-first decision.
For distributors and wiring-harness buyers working with Middle East B2B customers, this usually means a request that mixes two fixing families: push-mount fir tree clips for punched holes, and edge clip cable ties for flanges and hems. The five items in this range cover both families, and each is defined by a different set of numbers, so selection has to start with measurements taken on the real panel.
This guide explains how to read those numbers, which values are catalog data and which still need written confirmation, and what to send with an enquiry so the quotation matches the application the first time.
Round-hole fir tree clips: items 003 and 004
A fir tree clip pushes into a round hole and holds the bundle clear of the panel face. Item 003, Part No. ALSFT6-02, is listed with a specification of 5.9-6.5 mm, a unit weight of 0.48 g and packing of 500 pcs per bag. Item 004, Part No. ALSFT6L-03, is listed at 6-6.6 mm, 0.59 g and 500 pcs per bag. Both are described as push mount in a round hole.
Because the two ranges meet at the boundary, the part is chosen by measuring the hole rather than looking at it. A caliper reading at three points around the circumference, plus panel thickness and any paint or sealer build-up at the fixing point, gives the buyer something concrete to hold the supplier to.
The current catalog data for items 003 and 004 does not state material, temperature range or flammability class. Those values must be confirmed in the formal quotation or PI before a drawing is released, because a clip that suits a cool interior panel is a different question next to an exhaust-side component.
Edge clip cable ties: items 019, 021 and 026
An edge clip cable tie grips the edge of a panel flange, which removes the need to punch a hole and lets the harness follow a hem, a seam or a box section. Item 019 (ALSEC4-01) and item 021 (ALSEC9-01) are both listed for a panel thickness of 1-3 mm; item 026 (ALSEC23-01) covers 3-6 mm.
All three are listed as PA66, with a flammability class of 94V-2 and an operating temperature of -40 to 120°C. Unit weights are 1.07 g, 1.23 g and 1.47 g respectively; packing is 500 pcs per bag for 019 and 021, and 250 pcs per bag for 026.
On paper 019 and 021 share the same panel range, material and temperature data, and differ in part number and unit weight. The catalog does not define the bundle range or the head format, so the differences that matter on a real harness, such as bundle capacity, head clearance and insertion direction, need to be checked against a drawing and a physical sample before one part is committed to a whole project.
Read the mounting point before choosing a part number
Two questions settle most of the choice: is there already a hole, and is there an accessible flange edge within reach of the bundle. A hole already punched in an inner panel usually points to a fir tree clip; a flanged seam with no hole points to an edge clip. Where both exist, installation time and service access decide.
Pull direction deserves its own note. A tie loaded sideways against a sharp hem behaves differently from one loaded along a flange, and no catalog value replaces a sample trial on the actual panel. The same applies to edges with heavy paint, sealer or burrs, which change how the clip seats.
- Hole diameter, measured with a caliper at three points
- Panel thickness at the fixing point, including coating
- Edge condition: straight or curved, deburred, reachable by hand
- Bundle diameter range at the fixing point
- Distance to heat sources, moving parts and service points
- Direction of pull on the tie head under vibration
- Removal frequency: one-time assembly or repeated servicing
Heat, ageing and fluid exposure in Gulf conditions
The edge clip items carry a listed operating temperature of -40 to 120°C. That figure describes the material, not the environment at a specific fixing point; the temperature beside a turbocharger or an exhaust route is a location question the harness designer has to answer.
Where a fixing point sits close to a heat source, quote the measured or expected peak temperature in the enquiry and ask for the material declaration that applies to the selected item. Do not assume a certificate or test report exists for a given part: ask which documents are available for the items you intend to stock, and confirm the answer in writing.
Storage also matters in the region. Bags kept in a hot warehouse or in direct sun before assembly can affect handling, so keep packaging closed, off the floor and out of direct sunlight, and rotate stock so older bags are used first.
Packing, carton data and import preparation
Unit weights in this range run from 0.48 g to 1.47 g per piece, which is enough to estimate freight and carton gross weight once pieces per bag and bags per carton are known. Bag quantities are stated for each item; carton quantity varies by size and must be confirmed per order.
OEM labels and OEM packing are available, with MOQ and production time depending on the model and the packaging requirement. EXW and FOB may be offered depending on the quotation.
Keep the import file simple and complete. Confirm current import and labelling requirements with a local broker or authority in the destination country, and make sure the commercial documents agree with the packing list before shipment rather than after arrival.
Buyer checklist before requesting a quotation
Send the checklist as a single table so the quotation can be built line by line instead of against an average assumption. Values that depend on the order, such as final packing, weights and lead time, stay subject to the formal quotation or PI.

Frequently asked questions
Can one edge clip cable tie cover both 1-3 mm and 3-6 mm panels?
No. Items 019 and 021 are listed for 1-3 mm and item 026 for 3-6 mm, and the ranges are stated separately for a reason. Measure the flange thickness at the fixing point, including paint and sealer, and specify the item that matches that reading.
Do the fir tree clips have a stated temperature range?
The current catalog data for items 003 and 004 does not list material, temperature range or flammability class. Those values have to be confirmed in the formal quotation or PI, and the request should state the expected peak temperature at the fixing point.
Does a part number confirm that the clip fits a particular vehicle?
No. Part numbers are catalog references for comparison and ordering. They do not confirm vehicle fitment, brand authorization or original-equipment status. Fitment is established by checking a drawing and a physical sample against the actual mounting point.
What should accompany a sample request?
Send the measured hole diameter or panel thickness, the bundle diameter range, the quantity you expect per part number, the packing format you need and your target timing. With those inputs the sample set can be matched to the application rather than to the closest-looking item.
Can bags be supplied with our own label?
OEM labels and OEM packing are available. MOQ and production time depend on the model and the packaging requirement, so both are confirmed in the quotation for the specific items and label format.
