Fiber optic splice closure knowledge brief Published 04 Jul 2026

Prepared for preliminary research by the RIVO OPTICAL knowledge desk. Confirm cable count, splice capacity, sealing class, tray layout, protection sleeves and installation requirements against current standards and product documentation.

The draft angle (also called taper angle) of an LED module housing refers to the slight inclination designed into the vertical walls of the plastic base. It's typically measured in degrees (°) and ensures that as the mold opens, parts don't drag or scrape against the cavity walls. Here's why draft is indispensable: Shrinkage: As plastic cools inside the mold, it shrinks. This. Drafting can be done by length or by angle. Note: Draft length is not compatible with a Circular grid type with a Radial shift. When selecting Draft length, the value to define determines the size of the sewing surface created between two adjacent elements. This is a practice that is used, in applicable cases, when working with fiberglass.
