Open Splice Junction Box (5 Pack) - Quick One-Piece Splice Solution

In this review of the Open Splice Junction Box (5 Pack) the bottom line is simple: this is a practical, time-saving solution for electricians and DIYers who need to enclose open wire splices quickly and to code. The reviewer found the one-piece design and hinged lid cut installation time dramatically compared with traditional boxes, and the fact it is UL listed and made in the USA gives confidence when addressing a common safety issue. It is best for projects where speed, safety, and minimal rework are priorities.

Key Features

• One-piece design: The patent-pending single-body construction reduces parts to manage and makes handling and installation simpler on cramped jobs.
• Hinged lid: A lid that folds down to seal the splice eliminates the need to disconnect wiring and avoids redoing splices just to fit them into a box.
• Multiple side slots: Slots for wiring on four sides let you route conductors in and out without forcing or bending wires excessively.
• UL and CSA safety: Built from fire-resistant polymer and developed through laboratory testing to meet U.S. U.L. 514C and Canada CSA C22.2 #182 safety codes for reliable protection.
• Compact volume: Provides 25.8 cubic in of internal volume, offering adequate space for common splice combinations while staying compact for tight locations.
• Made in the USA: Domestic manufacture ensures consistent build quality and traceability for professional use.

Who It's For

This junction box is ideal for electricians, contractors, and competent DIYers who need a fast, code-compliant way to enclose open splices without reworking connections. It suits work in attics, crawl spaces, and finished interiors where access is limited and reducing time in uncomfortable locations is valuable.

It is less appropriate for installations that require deep, specialty enclosures or for situations demanding metal boxes, conduit fittings, or where larger splice capacity beyond the 25.8 cubic in is necessary. For heavy commercial conduit systems, consider an enclosure designed specifically for that environment.

Pros & Cons

Pros

• Fast, intuitive install thanks to the three-step process and hinged lid.
• Retains existing wiring so splices do not need to be disconnected, saving time and reducing error risk.
• Meets recognized safety standards and is made from fire-resistant polymer for dependable protection.
• Compact but adequate internal volume for common residential splices, with side slots improving routing.

Cons

• Polymer construction and 25.8 cubic in volume may not suit every commercial or high-capacity splice need.
• The one-piece design may limit internal reconfiguration compared with multi-part boxes in specialized situations.
