1. Single-ended thermoplastic closure
2. Fabricated by mixing the imported material and other chemical assistant agents (aging resistance & ultraviolet radiation resistance), an increase of service life
3. Base-to-dome seals on SJ-D-2 are mechanical for ease of installation and re-entry. No other sealing adhesive tape is needed.
4. Base and dome sealed with clamp and O-ring system
5. The splice trays are hinged for access to any splice without disturbing others trays
6. The inner parts and fixing parts are made of stainless steel
7. SJ-D-2 with an earthing device protect it from damage by lightning
8. Compatible with most cable types (single fiber or ribbon), and cable constructions (loose tube, central core, slotted core, modular). And the product can be used in any environment (aerial, buried, handhole, manhole) and in many applications (tap-off, expressed, branch, and repair)
9. No special tools are needed to open the closure, and it can be opened and used repeatedly.
