Crater 6380 | Chain Operated Roller Blind

System Technical Characteristics

Bracket surface painting treatment, matching decorative cover to hide the installation screws; The overall
appearance is small and exquisite.
Driving head up to 8 evenly distributed planet force reduction helical gears with a speed of 1:1.75, smooth
operation and labor-saving, and more durable service life under uniform load.
Mute drive head, tail plug pack adhesive shock absorption; Tail-seat bearing is more wear-resistant and quiet
for comfort.
The use of stainless steel bead chain, vertical feeling is good, can be installed up and down limit.
45mm tube with variable radius, fabric indentation free design, 6 reinforcing bars are designed, and the
bending resistance of high strength tube is good.
Optional side cable, tilt MAX15°, fabrics running smoothly up and down.
A variety of optional design with decorative bottom bar

Up to 8 evenly distributed planetary force reduction helical gears drive the head with a rate of 1:1.75, smooth operation and labor saving.The service life of uniform force is more durable.
Silent stainless steel beads with good vertical feeling, with transparent limit beads.
The gap of the fabric at the driving end is 18mm. Strengthens the connection of the tongue. The force is even and firm without rotation and pulsation.
Main material: PA66+GF30 polymer composite material, high strength, wear resistance, long service life.

Adopt steel shaft rebound design, fast spinning out, convenient loading and unloading.
POM wear-resistant and quiet.
Simple and exquisite appearance.

Reel variable radius fabric indentation free design, reduce the impact of fabric thickness; Four stiffeners to improve the strength of bending deformation.
High strength extruded profile, surface anodized treatment, the thickness of the tube up to 1.4mm.
Multi-style bottom rail design, full/half covered fabric structure, simple style.
Bottom rail slot type, the inner cavity can be added with steel rod counterweight, can keep the fabric flat and sagging, to ensure the fabric bottom does not wrinkle.
