The Buyer Decision
When you're shopping for building parts and replacements, the right purchase depends on the exact job you're doing. Two parts sit side by side in the market: a 4-pack of 5" x 5" steel safety railing mounting sockets for construction sites and a heavy-duty HVAC component from International Comfort Products. They're both legitimate building parts, but they're aimed at different trades. One anchors railing on a site; the other keeps an HVAC system running. The decision starts with your application, not just the price.
Quick Verdict
If you're putting up steel safety railing on a construction site, the 4-pack of 5" x 5" single mounting sockets from Mytee Products is the direct, job-specific option. If you need a heavy-duty HVAC component for a heating or cooling system, the International Comfort Products 1190664 is the replacement part to budget for. The two sit at different price points - $175.69 versus $655.71 - and they solve different problems, so the lower-priced option is only the right choice if it matches the job.

The $480.02 spread between the two reflects their different roles: one is a multi-piece railing mounting kit, the other is a single heavy-duty HVAC component.
Where Each Product Wins
- Right for construction safety: The 4-pack railing socket kit is built around a specific task - mounting steel safety railing. It gives you four casting-steel sockets in a silver finish, each sized 5" x 5", so you can set up multiple railing posts in one purchase.
- Right for HVAC replacement: The International Comfort Products 1190664 is a heavy-duty HVAC component listed as new with MPN 1190664. It belongs in heating and cooling equipment, not on a railing post.
Product Notes
4 Pack 5"X5" Steel Safety Railing Single Mounting Socket for Construction Sites

This kit is the pick if you need multiple mounting points for steel safety railing on a construction site. It includes four casting-steel sockets, each with a 5" x 5" footprint, in a silver finish, and it carries the Mytee Products brand. That makes it a practical way to handle several railing posts without ordering single mounting sockets. The $175.69 price covers the sockets only, so you're getting the mounting hardware, not the railing itself. It's a narrower product in that sense: the 5" x 5" size is fixed, so it's suited to railing posts that match that footprint. If that's your railing, this kit gives you a job-matched solution at a lower price than the HVAC component.
INTERNATIONAL COMFORT PRODUCTS 1190664 HVAC Component Heavy-Duty Construction

This is the choice when your project sits on the mechanical side: a single heavy-duty HVAC component from International Comfort Products, listed as new with MPN 1190664. The product name tells you its intended role - it's an HVAC component built for heavy-duty construction - and the MPN gives you a specific identifier to match against an existing part. At $655.71, it's the higher-priced item in this comparison, and it's not a multi-piece kit. It's a replacement part you'd order when you have an existing HVAC system and you're working from a part number. The identification centers on the MPN rather than dimensions, so it's a component for a professional who knows the application.
Final Choice by Use Case
If you're erecting steel safety railing and need mounting sockets, the 4-pack of 5" x 5" casting-steel sockets is the practical buy. If you're repairing or upgrading an HVAC system and need a heavy-duty component, the International Comfort Products 1190664 is the one to select. For general building-part stocking, the lower-priced railing socket kit is easier on the budget, but only if you have railing to install. Match the part to the job, and the right choice becomes clear.
