2021-04-03 - New J-Cup protector design for the Sorinex XL J-cups.
2021-03-26 - I've updated the design of all spotter arm protectors. They now should be stronger on the front corner than before. They will look more rounded on top than the current pictures. Also - Lime Green has been replaced with Neon Green. The color is similar by day, but it glows under UV light!
2021-03-17 - On popular request, I have designed a new spotter arm protector for the Rogue Infinity spotter arms. The J-cup protectors have also been refined for a better fit.
2021-03-09 - New design - J-Hook Covers for the Titan Fitness X-3 V2 J-Hooks.
Q. What is the "Economy" option?
A. I offer an "Economy" option for those who value function over form. Your color will be determined by whatever material I have on hand. They might have some printing defects that don't affect function. Turnaround times are usually faster with this option.
Q. What color will I get with the Economy option?
A. I can't tell you exactly, but here is the historical data of what customers have received.
Q. What are your products made out of?
A. Most of these products are made out of PLA with modifiers to enhance impact resistance. This material is tough enough to handle modest loads when used as designed.
Q. How durable are these parts?
A. The gym parts are less durable than the OEM UHMW, but when used as designed in a home gym setting, they should last for years. They are not designed to take a direct load or impact the way the UHMW does, rather, they are meant to absorb the bumps and scratches that occur with everyday use. They can crack or break if smashed directly with enough force.
Q. Will this part fit my _______?
A. These parts are only guaranteed to fit the models listed in the product page. If you find out that they fit something else, let me know!
Q. Will this color match my ______?
A. I do my best to take all photos under identical lighting conditions with artificial flash (5600K) and a high quality SLR camera. So long as your screen is accurate, the colors should be true-to-life. Contact me for custom color requests or if you would like a sample puck.
Q. Are you eco-friendly?
A. We strive to be as green as possible in our little operation. The primary material used is PLA made by NatureWorks. It is a bioplastic made out of plant oils. Packing materials are often reused or recycled based on what is on-hand, so don't be surprised if you get some unique boxes. All waste plastics are recycled in the appropriate streams. Unused materials are donated to other makers.
