Product Overview
Stainless-Steel 304/316 Wire Rope Cross Clip / DIN741 Wire Rope Saddle Clamp / Wire Cable Clamp – Model ZB7301 Series
RICHWITS ZB7301 gives you a precision-machined, DIN741-compliant clip that terminates wire rope with 360° grip and marine-grade corrosion resistance.
Investment-cast from 304 stainless steel (316 on request), then CNC-machined and passivated for lifetime immunity to salt-spray, humidity and chemical exposure.
Classic saddle + U-bolt + double-nut design grips 2–20 mm wire rope; forged base distributes load across full rope circumference.
Ten sizes deliver working-load limits from 80 kgf to 2 500 kgf—perfect for crane rigging, elevator cables, yacht standing rigging, shade sails or architectural tension systems.

FAQ
Q1: Will 304 SS really never rust?
A1: 304 resists most salt-air; choose 316 for continuous immersion—polish yearly to keep the shine.
Q2: What safe working load (SWL)?
A2: From 80 kgf (2 mm) to 2 500 kgf (20 mm); use 3–5 clips per wire end—safety factor 5:1.
Q3: How many clips per 10 mm wire end?
A3: Minimum 3 clips spaced 6× wire Ø (60 mm); 5 clips for critical lifting applications.
Q4: Will the saddle slip under vibration?
A4: No—torque 25 N·m (M10) + saddle orientation "live end on saddle"; tested 24 h vibration, zero slip.
Q5: Are spare 316 versions available?
A5: Yes—316 upgrade on request, MOQ 200 pcs, 30 % price adder.
Q6: Do you offer test certificates?
A6: DIN741 compliance cert, mill certificate for 304/316 SS, salt-spray report, and proof-load certificate supplied free on request.
