Reference#: 68294
Item#: 3M-BB2X24-8882


The BB2X24-8882 (Corning # 80611147838) Better Buried Closure uses a gravity fill method of encapsulating and protecting the cable splice. The Better Buried kits are simple to install and are offered with a full product offering to cover the complete cable ranges found in the outside plant. In addition, kits can be ordered with 4442 High Gel reenterable encapsulant. The 89 Series can also be purchased with 4407 Encapsulant for making a permanent, hard encapsulated closure with maximum water protection. The BB2X24-8882 kit is for use with 50-100 pair cable depending on the type of connectors used (discrete or modular).


The Better Buried Compound Compression Closure System used the compression method to force the encapsulant up the cable core to stop water ingress. The product is simple to install, comes with the spacer web and plastic wrap and is used to hold and force the encapsulant. The product is offered in different sizes to cover various cable ranges and can be easily extended and bricked.


Better Buried End Caps
Tapered end caps can be trimmed and slit for exact cable size required. Single, double and triple entry styles are available dependent on size. When adding a branch cable to an existing cable, grooved end caps can be easily split in the field and quickly released with Locking “H” strips provided in each kit.

3M Scotchcast™ Strain Relief Bars
Strain relief bars can be installed on a simple or double sheath cable to protect the splice from electrical interference and damage from the cable tension. The aluminum strain relief bar assemble includes hose clamps and an insulation sleeve.

3M Scotchcast Spacer Web 4430
Spacer web is designed to protect splice connectors by positioning them away from the closure walls. Better coverage is achieved because compound flows around the complete bundle.

Hose Clamps
Hose clamps secure the closure body and end caps.
